Dear ROOTers, I am doing histograms fitting with the Fit() method from TH1 class. As far as I understand the error used to do the fitting is the statistical error sqrt(N). True ? Actually my histograms were filled with events weighted (y=N*w), so I want the Fit() method to use another error than sqrt(y) that I believe it is using. Does anybody know how I should do this ? Thanks ! Ludyvine. -- Ludyvine Morand DAPNIA/SPhN - Bat 703 Piece 156 - Orme des Merisiers CEA Saclay - 91191 Gif-sur-Yvette cedex - FRANCE Tel : (33-1)01 69 08 87 19
