Profile: How do I create a Profile?
Profiling works on two sets of data namely the Analysis (or target) data set and the Base.
-
The Analysis is the set of data that you wish to measure the characteristics of.
-
The Base is the backdrop against which you wish to measure.
Creating a Profile can be summarised by the following stages:
-
Define the base set using any of the FastStats' methods of selecting records e.g. Selection tool, Venn tool, a saved reference number file etc.
-
Similarly, define the analysis set.
-
Specify the variables for consideration in the profile. (e.g. Selectors, Banded Date and Numeric, Queries or Query Sets)
-
Specify which type of profile to perform.
-
Build the profile.
If no selection is made for the base group then the entire database will be used to build the profile.
Scenario
As a worked example using the Holidays demonstration system, let's suppose we want to profile customers who have been to Italy across people who have spent more than £200 on a holiday. To do this we will use Italy holiday makers as the base selection and people who have spent >= £200 as the analysis:
Define the Analysis selection:
-
Create a new selection by dragging the Selection tool onto the FastStats workspace.
-
From the Bookings folder in the System, explorer, drag the Destination variable onto the selection window.
-
Select Italy in the list of destinations.
-
Drag and drop the Profile tool from the toolbox and onto the selection window.
Define the Base Selection:
-
Select the Base Selection tab from the top of the Profile window.
-
From Bookings folder in the System, drag the Cost variable onto the Base Selection window.
-
Enter >=200 in the Freeform box.
Define the variables to use in the profile then generate it:
-
Make sure you have the Profile tab selected at the top of the screen (i.e. not the Base Selection tab)
-
From the People folder in the System explorer, drag and drop each of the variables Title, Occupation, Income and Source in turn onto the Profile window.
-
Click the Build button to build the profile.
