Hi, Please check this article which details the method for comparison:
Statistica Sinica 17(2007), 1115-1137 TESTING FOR THE EQUALITY OF k REGRESSION CURVES Juan Carlos Pardo-Fern ́ndez, Ingrid Van Keilegom and Wenceslao Gonz ́lez-Manteiga Also, check some examples (http://www.stat.umn.edu/geyer/old/5601/examp/kolmogorov.html). I am not very familiar with non-parametric tests. A.K. ________________________________ From: Luis Fernando García Hernández <luysgar...@gmail.com> To: arun <smartpink...@yahoo.com> Sent: Monday, July 30, 2012 9:00 PM Subject: Re: [R] curve comparison Thanks both for your answer, Will, do you have any reference which shows me how how to perform this analysis? I´d like to know to find out how to do it. In my case data is similar to compare several diversity curves, I do not know if you are familiar with them. Related to the Kolmogrov Smirnov test, I´ll try, I did not know it allowed curve comparison. This is a great space to share questions, so thanks both for your answer! 2012/7/30 arun <smartpink...@yahoo.com> Hello, > >You could try some non-parametric tests for comparison such as >Kolmogorov-Smirnov test (ks.test() package: truncgof)or Cramer-von Mises test >(cvmts.pval() package: CvM2SL2Test). > > >A.K. > > >----- Original Message ----- >From: Luis Fernando García Hernández <luysgar...@gmail.com> >To: r-help@r-project.org >Cc: >Sent: Monday, July 30, 2012 1:38 AM >Subject: [R] curve comparison > >Dear R users, > >I have seven regression lines I´d like to compare, in order to find out if >these are significatively different.
