Hello together, Is there a tool to test the statistical differences between parameter estimates of an nlsList fit, with more than two groups? I am able to complete the nlme function for two groups after getting starting paramaters in nlsList, as seen below.
>fit.nlme <- nlme(rate ~ SSmicmen(conc, Vm, K), fixed=Vm+K~state, groups=~state, start=c(212, -52, 0.06,- 0.01), data=Puromycin) >summary(fit.nlme) However, I am unable to test the differences between more than 2 paramaters. My data set has 5 different groups and therefore has 5 different paramaeter estimates and I am not sure how to fill in the start=c() for more than 2 groups. Thanks Jens ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
