✦ Synopsis

We present a multilayer model for the interpretation of ARXPS data in which the total atom density of each layer is not constrained. We find that the variable density profiles can be successfully stabilized by the use of Tikhonov-c 2 regularization and a value for the regularization parameter for which the x 2 statistic for the goodness of fit to the data is equal to the number of independent observations in the data set.

Principal component analysis is a useful method for analysing data-matrices. By analysing separate class models, i.e. disjoint principal component modelling as in the SIMCA or FCVPC programs (developed for supervised and unsupervised principal component analysis respectively), the principal componen
