Define subset values
When you have selected a subset variable for an MGPS run, you must specify subsets, with each subset representing one or more values of the subset variable. For example, if you use Received Year as the subset variable, you can create one subset for each year except 1998, 1999, and 2000, which you group together into one subset. Oracle Empirica Signal generates a set of data mining results for each subset that you specify.
The source of subset values is either the source database or values that have been defined by data transformations in the data configuration. For example, if the source database contains report received dates, the creator of a configuration can transform the received dates into years, half-years, or quarter-years.
If a value for the subset variable is missing from the source data, the value of your user preference, Replace Missing Values with, appears in place of a value.
Note:
When specifying subsets, keep in mind that there is an iteration of MGPS for each subset. The more subsets you specify, the longer the MGPS run takes.Parent topic: Define subsets for an MGPS run
