Dear R users,I proceeded to a regression through the gls fonction (package nlme) with the following code:
>a1=read.table("total25.txt",header=TRUE)>a1$T=factor(a1$T)>m2=gls(Res~ModeF*T,a1)>m2>summary(m2)
I used gls fonction because it deals with heteroskedasticity and I would like you to confirm that I do not have to check for it after the summary procedure. It would seem logical to me but I am not sure what to do here.
Thank's for your help,
Rob.
