Our FastStats development team works using quarterly releases. Scroll down to see the FastStats quarterly releases from this year.

Note: Since the Q2 2023 release, all tiers of Apteco software now require a minimum of the .NET Framework 4.7.2 or later to be installed.

Note: Please see Notes for administrators for steps to be completed before applying a quarterly upgrade to your Apteco software.

FastStats Q4 2023 software release

New features

Analysis

New penetration mapping capability

Penetration mapping compares particular groups of customers by location.

This new functionality builds upon the capabilities of the modelling Profile tool, which allows you to find categories and characteristics of interest or over/under-representation within an analysis group and compare them to a wider base group. Now you can work in a similar way to search for and visualise geographical insight in your data using the Map tool.

The new Selections option, accessed via the mapping toolbar, is where you add your analysis selection and choose to compare it against, either your entire base, or optionally a specified base selection. You can select the insight measure to display and present the results very visually on a map.

The calculated metrics include:

As well as being able to compare two groups of people within your FastStats data - for example, your Sweden customers vs. all your customers - it is also possible to take records within your FastStats system and compare them against an outside population. For example, you might wish to compare the location of your own customer base against the actual population count in each postal area to find what percentage of the people in each area are already your customers. You can achieve this by using a lookup file that has one row for each postal area and contains the relevant geo-demographic information.

See Bing Maps: Penetration Mapping.

N% per variable sampling in selections

N per table (such as 1 per household) and N per variable (such as 1 per email) functionality has been available in FastStats for many years, but is now extended to provide a much simpler solution to a common sampling requirement - that is, to sample N% of records whilst maintaining the distribution across the underlying variable. For example:

On the left is a selection of 108,876 Directors, Managers and Professionals, broken down in a cube by Income Groups. On the right you can see the effect of sampling 10% per Income Group. The % Column of People metric shows that, with the new N% per variable functionality, the distribution across the Income Groupings variable remains constant.

Rather than looking for the percentage of records across the variable, you can also take the alternative approach of determining the total number of records you require:

The resulting cube shows the count and corresponding distribution of records based on a target sample of 1000 people.

See Selection: How do I make a N% per variable selection?

Cube, tree and word cloud conversions to map

For a cube, tree or word cloud which has a single geographic variable, such as Postal Area, you can right drag and convert into a map. The variable must be a selector and have the GeoFormat property set for this to be possible.

See How do I switch between cube-based visualisations?

Change to Map drivetime dialogue

When creating drivetime analysis, you now have two choices for selecting the origin of the drivetime - either the point you clicked, or the point you searched for. This can help to produce more accurate drivetimes, particularly when supplying the Bing Isochrone API with a centrepoint that is not near any roads.

See Bing Maps: drivetime calculations

Extension to Relative Transaction on the fly aggregation

The ability to include a third piece of transactional information was introduced for Rank, Recency and Pattern Match aggregations in the Q3 release. This is now extended to include Relative Transaction aggregations and, like Recency, allows you to specify two ordering variables and use the second one to break ties when the first one is equal.

See Aggregations on the fly - Relative Transaction

Expressions

Four new expression functions have been added:

  • InListAllMatches and IndexFromList - these new logical functions allow for all matches to be returned rather than just the first match found.

  • DateToNumber and DateTimeToNumber - allow you to convert a date or datetime into a numeric value.

General

FastStats Q3 2023 software release

New features

Analysis

Powerful extension to on the fly aggregation capabilities

For the ranking, recency and pattern match techniques, the on the fly aggregation processing mechanism is extended to provide the option of including a third piece of transactional information.

Custom colours in cube, tree and map thematics

In addition to all existing thematic options, you can now user define and set a custom sequence of colours for the bands displayed in a cube, tree or map. This is useful for presenting insight when the graduation of colour is not significant, but differentiating information in the display is beneficial. For example, to clearly indicate in a cube that, for average cost, <X is bad, X-Y is ok, and >Y is good, you might opt to colour the corresponding cells red, yellow and green:

You can similarly display records in a map or, alternatively, as demonstrated below, you may wish to assign colours to map shapes based on discrete values. The following visualisation displays a parliamentary map coloured to highlight the winning political party for each area:

See Custom Colours in Cube, Tree and Map Thematics.

Custom labels in map thematics

The introduction of custom colours on a map also brings the ability to set up corresponding custom labels for each of the bands in your thematic shading. These labels are visible in the map legend and help to provide further meaning to user defined colours.

See Bing Maps Shaded Map - Custom Thematic Labels.

Expressions

New context sensitive help in the expression window provides an explanation and worked example for each function.

Scheduled task error notification

In addition to notifying the task owner, you can now specify a list of additional email addresses to which a notification should be sent if a scheduled task errors.

General

Bing transaction logging

Bing transactions are now recorded and stored in CSV files, allowing administrators to easily:

  • Track and verify usage

  • Provide clarity on transaction counts and allowances

For more information, see the Bing transaction logging technical update.

FastStats Q2 2023 software release

New features

Modelling

New Incremental Insight measure

Your ability to identify the best behavioural features to use in a model is extended with the introduction of a new Incremental Insight metric. This single measure allows you to choose dimensions which are both predictive and diverse. It is based on the existing Insight PWE measure, but accounts for the associations between different dimensions. When building the dimension results, there is an additional option which allows for incremental insight to be calculated:

Selecting the top dimensions based on Incremental Insight results in a broader range of variables which would not otherwise be chosen. Shown graphically, you can see that, whilst the top dimensions may be individually lower in Insight PWE, collectively they provide more diverse insight and can produce a model which captures more aspects of a good prospect:

See Incremental Insight.

Bubble chart visualisation

When you select to colour by Insight PWE in the Chart options dialog, scatter charts now display as bubbles to show both the Insight PWE using colour, and the Insight Coverage using size:

See Chart Options.

Insight PWE metric available in standard Profile

You can optionally add and display the Insight PWE metric as a column in a standard profile.

See Standard Modelling Development Update Q2 2023.

Analysis

Territories wizard improvement

When working with the option to link a new shapefile to an existing selector variable, FastStats now automatically checks for categories in the variable which do not match those in the shapefile. Once identified, you have the opportunity to update them as part of the wizard process.

See Territories wizard.

Mapping usability improvements

The following usability improvements allow you to create maps more easily:

  • You can now drag variables directly on to the Statistics panel on a map layer, rather than having to use the Add Statistics button.

  • Changing the primary statistic on a thematic map layer automatically updates the thematic shading without the need to rebuild the map.

  • On a thematic map layer, you can now right click on the Geographic Variable drop-box to easily access, select and add any available selector variables with a 'GeoFormat' property set.

  • On a plot map layer, you can now right click on the Geographic Variable drop-box to easily access, select and add any selector or text variables with a 'GeoFormat' property set.

  • In Map wizards, where you need to specify latitude and longitude variables, you can now right click and access a menu option that allows you to select and add variables which are marked with the relevant 'GeoFormat' property.

  • When using the Location Geocoder wizard, you can now select a check-box to confirm that your geographic variable is a UK postocode. This allows the virtual variable to be generated using the UKPostcode expression rather than using Bing Geocode. The results are returned significantly faster and without incurring Bing transaction costs.

See What's New in FastStats.

Bing API caching

Bing API Isochrone: Drive zones created using the mapping wizards are now stored. This means that, when editing the variable, you do not incur new Bing API transactions for zones that have previously been calculated.

You can configure zones to have an expiry period after which they are then recalculated.

BIng API geocoding: Searching for locations on an interactive map, or through specifying centrepoints in the Map wizards, incurs Bing API geocoding transactions. From Q2 2023, specifying a centrepoint in 'Latitude.Longitude' format (for example, 52.281806,-1.588657) is treated as valid location information. This is a user-configurable property.

If you have to request a geocoded location from the Bing API, the resulting latitude and longitude is stored and can be reused if you request it again. This is supported in the interactive map search and the map wizards’ Centrepoint step.

See Bing API.

Import Data wizard enhancement

When creating a selector type variable from a data file, previously both the codes and descriptions for the resulting variable were taken from the data column and were the same. You can now specify a second column in the data file and use this to generate the category descriptions for the resulting variable.

See Import Data Wizard.

Expressions

New and updated expression functions

There have been updates to existing, as well as the addition of new expression functions, including:

  • Selector functions: VarSelectNth and VarSelectCodeNth

  • DateTime list functions: FirstDateTime, LastDateTime and NthDateTime

Security

Transition from SHA-1 hashing algorithm for enhanced security

Note: Due to the deprecation of the SHA-1 Security Hash Method, Apteco strongly recommends transitioning to a more secure option, such as SHA-256.

If your FastStats system is currently set to the SHA-1 hash function, then you must upgrade to a preferred hash method promptly. This upgrade ensures that you are using the most secure hashing method and avoid any security issues for using a deprecated service.

See Change hashing algorithm for FastStats systems.

FastStats Q1 2023 software release

New Features

Modelling

Generate multiple behavioural features with different criteria

The selection of behavioural features has the greatest impact upon the final quality of a data model. Whilst recent development has focussed on charts and metrics which help you to assess existing features in order to identify subsets which might be predictive or diverse, this release makes it easier to generate alternative behavioural features. This includes the ability to generate multiple behavioural features with different criteria; simple, combination, or modifying multiple existing dimensions. The new features are generated using one or more existing features as a template. Each new feature mirrors an existing one and adds one additional criterion.

See Generating multiple Behavioural Features with different Criteria.

Use of cube tool to analyse complex customer journey selections

Complex customer journey selections can be generated directly from the analysis you carry out using the FastStats Modelling Environment, providing the flexibility to adjust the analysis date in the selection and easily study different ranges of transaction history.

You can now drag and drop a FastStats Cube onto these selections and carry out further, powerful analysis on the events within a customer journey.

See Using a Cube to analyse a customer journey selection.

Other developments include:

More flexible control of building dimensions

  • Simpler user workflow with the "Use" status

  • The ability to thematically colour multi-dimension charts by Insight PWE

  • Updates to the right-click menu options

  • Edit Details option available in standard modelling

  • Chart and Build options are saved with the Modelling Environment

See Modelling Development Updates for more information.

Analysis

New options for referencing a file of values to use in a selection

The existing ability to import and reference a file of values (for example text or URN) has been extended in this release, with support added for selector and numeric variables.

  • For selector variables there is a new option to reference the codes in the file at the time a selection is actually run. This is in addition to the pre-existing import option which takes the current values in a reference file and matches those current values to the relevant codes in order to select them.

  • Numeric variables are supported as a set of ranges. Any updates to the reference file are also reflected when the selection is rebuilt.

See Selection: How do I import values by reference?

Map wizards improvements

Drive Zone

When creating drive zones for multiple centrepoints using latitude and longitude, you now have an additional option to create a single multi-response (flag array) virtual variable for all points.

You can use this variable to quickly and easily create thematically shaded drive zone visualisations using the Map tool.

See Drive Zone Wizard.

Territories

It is now possible to see a sample of a selected shapefile’s features and related values, allowing you to easily select a field to be used for the resulting virtual variable categories.

See Territories Wizard: Json File Details.

Removal of Microsoft MapPoint

In the Q4 22 release notes we announced that support of MapPoint would cease from Q1 23. As a result:

  • The Settings page in the Drive Zone and Point to Point wizards has been removed

  • It is no longer possible to select Map Regions in the FastStats Tools-Options

  • You can no longer select to use Routes API as a drivetime option in the Map tool

Expressions

New option to set GeoFormat via Calculate Expression wizard

Recent developments in the mapping wizards often require the use of latitude and longitude variables. Where such variables are not already present in your system data, you can use the UKPostcode expression function to turn a postcode into a latitude or longitude reference. In such cases, the Choose Data Type step of the Calculate Expression wizard now also allows you to set the GeoFormat on these virtual variables so that you can then use them in the mapping wizards.

See Calculate Expression Wizard.

New and updated expression functions

There have been updates to existing, as well as the addition of new expression functions, including:

  • NthDate: a new date list function to return the Nth date in a list of dates.

  • NthDistinct and NthDistinctIndex: two new sorting functions which work with numbers, dates or datetimes to sort into ascending order and select the Nth distinct or Nth distinct index parameter respectively.

See What's New in FastStats?
