Method Detail

makeMetricBuilder

public hex.ModelMetrics.MetricBuilder makeMetricBuilder(java.lang.String[] domain)

Specified by:

makeMetricBuilder in class hex.Model<CoxPHModel,CoxPHModel.CoxPHParameters,CoxPHModel.CoxPHOutput>

schema

public water.api.ModelSchema schema()

get_params

public final CoxPHModel.CoxPHParameters get_params()

toString

public java.lang.String toString()

Overrides:

toString in class hex.Model<CoxPHModel,CoxPHModel.CoxPHParameters,CoxPHModel.CoxPHOutput>

toStringAll

public java.lang.String toStringAll()

score0

public double[] score0(double[] data,
              double[] preds)

Predict from raw double values representing the data

Specified by:

score0 in class hex.Model<CoxPHModel,CoxPHModel.CoxPHParameters,CoxPHModel.CoxPHOutput>

Parameters:

data - raw array containing categorical values (horizontalized to 1,0,0,1,0,0 etc.) and numerical values (0.35,1.24,5.3234,etc), both can contain NaNs

preds - predicted label and per-class probabilities (for classification), predicted target (regression), can contain NaNs

Returns:

preds, can contain NaNs
