Webwant to focus the attention on the model PMF (Positive Matrix Factorization). The reason we are interested in PMF is its property to be a non data-sensitive technique that can manage and resolve inhomogeneous data-sets without any previous univariate analysis. In geochemical data-set, it usually happens that elements or compounds WebPMF2 (Paatero, 2000) was originally used. In the late 1990s, a more flexible program was developed (Paatero, 1999), known as the multilinear engine (ME). This program is currently in its second version and is referred to as ME-2.
