[R-sig-ME] compareFits() for residuals

[Christoph Scherber]

Dear all,

Suppose I want to compare the residuals of two lme fits using the compareFits() function. Is this possible (in principle)?

I end up with an error message here:

fm1 <- lme(distance ~ age, data = Orthodont)
fm2 <- lme(distance ~ age, data = Orthodont, weights=varPower())
compareFits(resid(fm1),resid(fm2))

Many thanks,
Christoph
