OraGLMSettings
is the super interface for GLM classification and regression algorithm settings interface. It defines the common GLM setting, that includes:
For classification models, the diagnostics table will have the following schema:
For regression model, diagnostics table will have the following schema:

public java.lang.Boolean useRidgeRegression()
true
when ridge regression is enabled. Otherwise returns false
. Returns null
when the system determines the ridge regression to be enabled or disabled.public void useRidgeRegression(java.lang.Boolean enableRidgeRegression)
true
. Otherwise ridge regression is diabled. When specified as null
system determines whether to enable/disable ridge regression.enableRidgeRegression
