Dear all,
Is it possible with two random effects in lme()?
lmefit1<- lme(Handling ~ Mass + factor(Prey)+ Mass*factor(Prey), random = ~
1 |Place+Age)
Here I use Place as random effect, but I also want to add Age as a random
effect. Since there could be an effect of Age (continous variable), but I
like to control for it rather than locking at the effect of Age on handling
time, since Mass and Prey type are of main interest.
Regards Kes,
