See http://www.statsoft.com/textbook/stdisfit.html There are several approaches you can use - Chi-square, Q-Q plots, P-P plots, various tests (Kolmogorov-Smirnov, Shapiro-Wilks' W) etc.
HTH, b. -----Original Message----- From: Angela Re Sent: Wednesday, December 22, 2004 9:13 AM To: [EMAIL PROTECTED] Subject: [R] how to fit in R Good morning, in my work I need to study data distributions and so I need to fit the experimental distribution by theoretical curves such as normal, Poison, binomial and so on. I'd like to know, given a vector of data, for example x<-rnorm (1000, 10) if they follow a normal distribution. I'd like to do a fit (to estimate the parameters of the theoretical distribution) and then a goodness test. Can you suggest me any R package or manuals about this issue? The documentation on the R-guide isn't sufficient to me. Thank you of your help, Angela ______________________________________________ [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
