AI-GEOSTATS Dear Sotiris, There was no reply with any magic solution.
In addition to the reply from Sebastiano Trevisani which was also sent to the list, I received the following mail from Monica Palaseanu-Lovejoy (see below). It is helpful but not exactly what I was looking for. Best regards Gregoire " I am not sure this works, but maybe if you do a multivariate comparison of the different variables and use a robust correlation coefficient it may give you some ideas if the 2 or more variables behave the same in space. it is a routine already in R which does exactly that, called "mvoutlier: This packages was made for outlier detection using robust estimations of location and covariance structure" by Moritz Gschwandtner and Peter Filzmoser and http://www.statistik.tuwien.ac.at/public/filz/ R is a free statistical software - it is equivalent with S-PLUS. Let me know if it works." __________________________________________ Gregoire Dubois (Ph.D.) European Commission (EC) Joint Research Centre Directorate (DG JRC) WWW: http://www.ai-geostats.org "The views expressed are purely those of the writer and may not in any circumstances be regarded as stating an official position of the European Commission." -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of S.
