Hi, I want to calculate PLS package in R. Now I want to calculate R, MSEP, RMSEP and R2 of PLSR and PCR using this. I also add this in library of R. How I can calculate R, MSEP, RMSEP and R2 of PLSR and PCR in R. I s any other method then please also suggest me. Simply I want to calculate these value. Thanking you. -- Nitish Kumar Mishra Junior Research Fellow BIC, IMTE...

...(PCR). Features of the package include - Several plsr algorithms: orthogonal scores, kernel pls and simpls - Flexible cross-validation - A formula interface, with traditional methods like predict, coef, plot and summary - Functions for extraction of scores and loadings, and calculation of (R)MSEP and R2 - A simple multiplicative scatter correction (msc) implementation - Functions for plotting predictions, validation statistics, coefficients, scores, loadings, biplots and correlation loadings. The main changes since 1.1-0 are - predict() now handles missing data like the `lm' method...

Dear R user, I am looking for a code on double cross validation in LASSO , one for optimizing the parameter and other one is for MSEP. If any one have it, please foroward to me. I am using different package like LARS, chemometric etc. Thanks in advance Alex [[alternative HTML version deleted]]

...y the formula interface and internal structure are apt to change in future versions. The software should, however, be fully usable in its present form. `lspls' currently includes fit and cross-validation functions with formula interfaces, a predict method, and plots of scores, loadings and (R)MSEP values. Suggestions, bug reports and other comments are very welcome. -- Sincerely, Bj??rn-Helge Mevik _______________________________________________ R-packages mailing list R-packages at stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-packages
