Abstract

This paper describes a robust centroid method, which is a variant of principal component analysis. A genetic local search algorithm is presented to perform the calculations. Simulations are carried out to appraise the performance of the genetic local search algorithm. A real data set with missing data and multiple outliers is analyzed.
