Multi-block PLS modeling for L-shape data structures with applications to mixture modeling

In some situations blocks of data are available from different sources. These data matrices often have no common dimension and are connected in a T- or L-shape structure. The example treated in this paper involves mixture modeling where blocks of data are available on the final product properties (Y), on the process conditions used to manufacture the products (Z), on the ratios of raw materials used in the formulations (R) and on the properties …
