I am using the pls-toolbox. The dataset is made up of: X [420x12] and Y [420x1]. I do everything and choose 5 LVs.
On the report there are the various folders, in the loads what do the 4 matrices present (those in the photo) correspond to?
(The (2,2) è 5x1)

PLS Toolbox? That looks like it might be a third-party commercial toolbox, https://eigenvector.com/software/pls-toolbox/ ?

loads: Contains factors recovered for the data. In the case of PCA or PLS models, the rows are the "scores" and "loadings" of the data. For PARAFAC, it is the loadings of each mode. The size of the loads field will be dxj, where d is the number of modes (dimensions) and j is the number of blocks of data used by the model (Table 1). PCA models will be 2x1 (two modes, one block), PLS models will usually be 2x2 (two modes, two blocks), PARAFAC will often be dx1 where d is at least 3. Other model types follow this same pattern.
