Abstract

Principal component analysis (PCA) is one of the most widely used statistical techniques for data dimension reduction. And a robust technique on PCA when data contains outlier is an important problem. In this paper, we consider the problem of robust PCA based on Minimum Covariance Determinant (MCD) mean and covariance matrix estimator. We aimed to look at the behavior of the principal component scores of robust PCA using MCD through their graphical plot of the first and the second PCS. The effect of outliers on PCA is studied by comparing the mean square error (MSE) resulted by MCD and by classical method in presence of outliers.
