Abstract
A new procedure for identification of outliers in Tucker3 model is proposed . It is based on robust initialization of the Tucker3 algorithm using Multi variate trimming or Minimum covariance determinant. The performance of the algorithm is tested by a Monte Carlo study on simulated data sets and also on a real data set known to contain outliers. (C) 2001 Elsevier Science B.V . All rights reserved.
