Method Detail

asBinary

BinaryLogisticRegressionSummary asBinary()

Convenient method for casting to binary logistic regression summary. This method will throw an Exception if the summary is not a binary summary.

Returns:

(undocumented)

featuresCol

String featuresCol()

Field in "predictions" which gives the features of each instance as a vector.

probabilityCol

String probabilityCol()

Field in "predictions" which gives the probability of each class as a vector.
