Method Detail

train

public boolean train(boolean stats)

Description copied from interface: StatisticalModel

Perform multi-linear regression using the Ordinary Least Squares method. Solves y = XB + e using b = inv(X'X)X'y

Specified by:

train in interface StatisticalModel

Overrides:

train in class PLSReducer

Parameters:

stats - calculate values for statistical analysis

Returns:

true if the regression succeeds.

calcG

protected double[] calcG(double[] vec,
                         int nonZero)

computeLambda

protected double computeLambda(double[] vec,
                               int noNonZero)
