--zScoreGroup

Switch

--zScoreGroup

Description

Outputs a certain group's zScore for all feats, which group is determined by the boolean outcome value [MUST be boolean outcome]

Argument and Default Value

No argument. Boolean switch, default: False.

Details

Used with --correlate in place of the default correlation metric; --IDP takes priority over this switch if both are given, and this switch takes priority over --AUC. The single outcome in --outcomes must be boolean. For each feature, reports that feature's group-level value for the (first) group whose outcome is True — this is meant to represent that group's z-score relative to the rest of the population, so it is most useful when exactly one group has a True outcome.

Other Switches

Required Switches:

• --correlate

• A single boolean --outcomes field

Example Commands
