mixed model
Hello all,
I have problem with setting up random effects.
I have a model:
y=x1+x2+x1*x2+z1+z1*x2
where x1, x2, x1*x2 are fixed effects
and z1, z1*x2 are random effects (crossed effects)
I use library(nlme) 'lme' function.
My question is: how I should set up random effects?
I did
lme(y~x1+x2+x1:x2, data=DATA, random=~z1+z1:x2, na.action='na.omit')
but it did not work.

partial SS for anova
Hello,
I use lme4 package.
library(lme4)
fit=lmer(y ~ time+dye+trt+trt:time + (1|rep), data=dataset, na.action='na.omit')
anova(fit)
The anova gives sequential F-tests and sequential SS.
My question is: how I can get partial F-tests and partial SS?
For lm (not lmer)
anova(lm(y~x+z))
we can use
anova(fit, ssType=3)
but it is not work for lmer.
Natalia.
