Constructor Detail

CoxPH.CoxPHModel

public CoxPH.CoxPHModel(CoxPH job,
                Key selfKey,
                Key dataKey,
                Frame fr,
                float[] priorClassDist)

Method Detail

get_params

public final CoxPH get_params()

Overrides:

get_params in class Model

job

public final Request2 job()

Overrides:

job in class Model

progress

public float progress()

Specified by:

progress in interface Job.Progress

score0

protected float[] score0(double[] data,
             float[] preds)

Description copied from class: Model

Subclasses implement the scoring logic. The data is pre-loaded into a re-used temp array, in the order the model expects. The predictions are loaded into the re-used temp array, which is also returned.

Specified by:

score0 in class Model

initStats

protected void initStats(Frame source,
             FrameTask.DataInfo dinfo)

calcCounts

protected void calcCounts(CoxPH.CoxPHTask coxMR)

calcLoglik

protected double calcLoglik(CoxPH.CoxPHTask coxMR)

calcModelStats

protected void calcModelStats(double[] newCoef,
                  double newLoglik)

calcCumhaz_0

protected void calcCumhaz_0(CoxPH.CoxPHTask coxMR)

makeSurvfit
