Method Detail

copyGLMCoeffs

public static void copyGLMCoeffs(GLMModel glm,
                                 GAMModel model,
                                 GAMModel.GAMParameters parms,
                                 int nclass)

gamNoCenterCoeffLength

public static int gamNoCenterCoeffLength(GAMModel.GAMParameters parms)

Find the number of gamified column coefficients. This is more difficult with thin plate regression smoothers. For thin plate regression smoothers, each smoother will have columns _numKnots + _M

Parameters:

parms -
