pls.pcr compared to Unscrambler
...Has anybody ever tried to compare pls regression outputs from the pls.pcr R-package developped by Wehrens with outputs from the Unscrambler software developped by CAMO company ? I find very different outputs and wonder if this comes from differences between methods/algorithms SIMPLS (pls.pcr) and PLS1 (Unscrambler).

Confidence intervals PLS prediction
I have switched from The Unscrambler to R for pls regression analysis and have been able to calculate scores, coefficients, RMSEP from a large number of PLS1 and PLS2 models. The ultimate goal is to use these models for predicting unknown samples, which again is straight-forward with the built-in predict() function. However, I?m struggling with prediction uncertainty (i.e. confidence intervals) on predicted values (as an estimate on the reliability of t...
