Dear list members; Is it possible to account for serial correlation in PLS modeling framework? Does anyone know if there is any published work on this topic? The situation is the following: I'm working with solid wood samples and several spectra have been collected from these samples. I expect those spectra to be correlated because they come from the same sample, so I'm not sure how to account for that. In traditional linear (or non-linear) regression models is possible to do that by specifying the structure of the variance-covariance matrix but I'm not sure how to extend that idea to PLS regression. Any comment will be appreciated. CM |
