This chapter highlights some typical examples of research themes in the chemometrics community. Up to now we have concentrated on fairly general techniques, found in many textbooks and applicable in a wide range of fields. Several other topics, some of them more specific to the field of chemometrics, combine elements from the previous chapters and warrant a separate section. We start with two examples dealing with outliers and noise, respectively. Robust PCA is an attractive method to identify outliers in multivariate space, at a modest computational cost.
