PO-PLS and SO-PLS are a collection of methods for multiblock regression (data fusion) developed at Nofima. This toolbox contains MATLAB functions for model fitting, cross-validation, prediction and plotting of results. An example script and a data set are also included for illustration, along with a short description and documentation of the main functions. All functions are based on the saisir data structure. For a detailed description of PO- and SO-PLS,see e.g:
