discriminantnode properties

Last updated: Jan 18, 2024

Discriminant node icon Discriminant analysis makes more stringent assumptions than logistic regression, but can be a valuable alternative or supplement to a logistic regression analysis when those assumptions are met.

Example

node = stream.create("discriminant", "My node")
node.setPropertyValue("target", "custcat")
node.setPropertyValue("use_partitioned_data", False)
node.setPropertyValue("method", "Stepwise")
