Use of nesting in lmer- error in numerical expression
...ested? That is, when there are e.g. 60 different nests
and 40 mothers. Do R then take into account that each mother can have
multiple broods? In that way the nesting seems redundant..?
Thanks for all help!
Best regards,
Arild

change of variance components depending on scaling of fixed effects
...ut I do not understand why there is such a massive
difference in the variance components.
Note that the first and last example has the same estimates of variance
components, but that the estimated scale is massively different.
All help is highly appreciated.
Thanks very much,
Arild
