Hi everybody,
I'm having problems with the logit.mixed model, or mixed models in general. I
want to estimate fixed effects parameters for the random effect. The vignette
says that you can do this by specifying gamma with tag(z1, gamma | g), but I get
".deparseTag(TT.vars[[vind]]) : wrong use of tag function!".
Questions: Am I missing something? Is this working as intended, or at all?
Thank you in advance.
Steffen
Here's the full code:
m3a <- zelig(formula= list(mu=abstention ~ age + [...] +dEUdir +
tag(1, gamma | ccode), gamma=~tag(years |ccode)), model="logit.mixed",
data=data04)
Others are having the same problem...
