Dear Rooters! I have got the following problem with fitting a histogram. I want to use an exponetial fit like a*(x-const)^b where a and b are fit parameters. b is between 0 and 1. I couldn't see any result with such a fit. I tried the following: (1) a*sqrt(x-const) what worked fine, then I tried (2) a*(x-const)^(1/2) what DOES NOT give a fit. Actually I don't see any mathematical difference between (1) and (2). Where is my mistake? Yours Falk P.S.: I am running Root version 3.03/09 10 October 2002 under i386_linux24 based on the SuSE 7.2. ++++++++++++++++++++++++++++++++++++++++++++++++++++ + Falk Karstens + + Abt. Prof. A.
