SCREENING Subcommand (ADP command)

The SCREENING subcommand specifies settings for excluding unsuitable fields.

PCTMISSING = YES(MAXPCT=value) | NO. Screen out fields with too many missing values. Fields with more than MAXPCT missing values are removed from further analysis. Specify a value greater than or equal to 0, which is equivalent to deselecting this option, and less than or equal to 100, though fields with all missing values are automatically excluded. The default is 50.

UNIQUECAT = YES(MAXCAT=integer) | NO. Screen out nominal fields with too many unique categories.Nominal fields with more than MAXCATcategories are removed from further analysis. Specify a positive integer. The default is 100.

SINGLECAT = YES(MAXPCT=value) | NO. Screen out categorical fields that are nearly constant. Ordinal and nominal fields with a category that contains more than MAXPCT of the records are removed from further analysis. Specify a value greater than or equal to 0, equivalent to deselecting this option, and less than or equal to 100, though constant fields are automatically excluded. The default is 95.
