Thank you for the reply! I need to use it in the package for constructing the contrast matrices. Renaming a variable like y2 - y^2 will not be a solution for me... Will try to look whether the function dummy.coef can be modified to work this issue. With best regards, Alexandra -Original

Re: [R] Nonparametric k-way ANOVA

Hello, Vincent, you may want to take a look at Nonparametric methods in factorial designs by Edgar Brunner and Madan L. Puri in Statistical Papers 42, 1-52 (2001). There is the R-package nparcomp for one-way layouts, but the paper goes further (and mentions another software) and is maybe a

Sylvie: I do not know whether your system lacks sufficient power, but its user -- you -- may. The models you are trying to fit are complex and nonlinear, and possibly depending on your data -- do you have a lot of missingness? How large are your data sets? Can they support your models -- you

Re: [R] What computer power for GAMM models

1) The model is far too complex. I have trouble imagining a system where the trend potentially uses 49 degrees of freedom and yet the unexplained variance within years follows an AR(7). It looks like you have time points within years over many years; is that why you are trying to use such a

Re: [R] Nonparametric k-way ANOVA

Thanks to all!! Gerrit, thank you for the reference. I was looking for something like that, but I was not able to find it. I partially agree with some of you, who said that nonparametric k-way ANOVA is a little bit of contradiction, but I just wanted to have an alternative to classical ANOVA.

Re: [R] Revo R for Arima Implementation

Your question is pretty well totally opaque to me. Describe the model you want to fit in mathematical terms, rather than referring to The Package That Must Not Be Named. This is the ***R*** list. It is possible that you might want to make use of the seasonal argument to the arima()
