SimPLS

When calling SimPLS the user has to provide the following parameters:

X0	the data matrix containing the independent variables
Y0	the data matrix containing the response variable(s)
NFact	the number of factors used to estabplish the PLS model
Standardize	a flag to control the scaling of the independent data (TRUE = standardize data, FALSE = mean centered data)

After completion SimPLS returns the following results:

ScoreX, ScoreY	the scores of the rotated X and Y space
LoadX, LoadY	the loadings of the rotated X and Y space
WgtX	the loading weights (see the paper of de Jong for details)
OrthoLd	the orthogonal loadings
varX, varY	the amount of explained variance in X and Y
RegCoeffs	the final regression coefficients

SimPLS increments the global variable ProcStat  and calls the feedback routine MathFeedBackProc in order to allow feedback to the user during time consuming calculations. In total ProcStat is increased by 100. The SimPLS procedure can be terminated by setting the global variable AbortMathProc to TRUE.

Hint:

While using SimPLS for special cases is perfectly OK, the "normal user" should rather use the class TPLSModel which is much more easier to apply and provides more features, including cross validation.
