Abstract: A method based on the idea of projection-pursuit is introduced for obtaining principal components that are robust and sparse [3]. The term robust refers to resistance against outlying observations, while the expression sparse means that some of the principal component loadings will be forced to zero values. In that way, the resulting method is insensitive to outliers in the data, and due to the sparse loading pattern, results are simpler to interpret.
