Hello,
I am trying to make the switch from SAS, and I have a fairly elemental
problem with syntax using the nlme package for analyzing mixed models.
There was a previous question on this topic posted to this list, so I
apologize for redundancy, but I didn't understand the advice given to
Host (fixed)
Sire (random)
Dam nested within Sire (random)
Host * Sire (random)
Host * Dam within Sire (random)
So without the interactions I have:
hogmodel = lme(gain ~ host, random = ~1|sire/dam)
If I understand correctly, that sire/dam term gives me both
Sire and Dam within Sire
