Constructor Detail

GLMValidation

public GLMValidation(Key dataKey,
                     double ymu,
                     GLMParams glm,
                     int rank)

Method Detail

regularize

protected void regularize(double reg)

makeKey

public static Key makeKey()

add

public void add(double yreal,
                double ymodel)

add

public void add(GLMValidation v)

nullDeviance

public final double nullDeviance()

residualDeviance

public final double residualDeviance()

nullDOF

public final long nullDOF()

resDOF

public final long resDOF()

auc

public double auc()

aic

public double aic()

computeAIC

protected void computeAIC()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

finalize_AIC_AUC

protected void finalize_AIC_AUC()

computeAUC

protected void computeAUC()

Computes area under the ROC curve. The ROC curve is computed from the confusion matrices (there is one for each computed threshold). Area under this curve is then computed as a sum of areas of trapezoids formed by each neighboring points.

generateHTML

public void generateHTML(java.lang.String title,
                         java.lang.StringBuilder sb)
