That will lead you to fit.dist{gnlm} and fitdistr{MASS} Cheers Francisco >From: [EMAIL PROTECTED] >To: [email protected] >Subject: [R] question from environmental statistics >Date: Thu, 14 Jul 2005 14:06:45 -0700 > > > >Dear R users >I want to knw if there is a way in which a raw dataset can be modelled by >some >distribution. besides the gof test is there any test involving gamma or >lognormal that would fit the data. > >thank you > >-dev ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
