Biplot classic is based on the singular values decomposition (SVD) of the matrix of data X. Conventionally it is constructed from obtained markers of a Principal Component Analysis (PCA) using XTX. This solution is susceptible to the presence of outliers in X. In this work a method to obtain a Robust Biplot, by means of alternate regressions, is presented, with which the potential influence of outliers in X is solved.
