Good morning
If I run
<<<
susan.lsmixed.out <- zelig(formula = unprot_vag_sex ~ married + age + TREATMENT.ARM*time + highest_grade + income + tag(1|id),
data = susanMI.out$imputations, model = "ls.mixed")
summary(susan.lsmixed.out)
>>>>
I get an error
Error in x$coef : $ operator is invalid for atomic vectors
Searching the archives, I see that others have had similar problems. Is there a workaround?
summary(susan.lsmixed.out[[1]])
works fine; should I then average across the five imputed data sets?
thanks!

I'm running a logit model using the zelig package in R:
z.out <- zelig(trade961a ~ age962 + education962 + personal962 + economy962 + partisan962 + employment962 + union962 + home962 + market962 + race962 + income962, data=data96, model="logit")
The dependent variable, trade961a, is a dichotomous factor variable. All other variables are numeric.
I am interested in personal962, which is:
> str(personal962)
num [1:1714] 3 3 1 1 1 2 3 2 2 1 ...
so I run the following to simulate the probability of supporting international trade when personal962 is 1 (better):
x.out <- setx(z.out, personal962=1)
I get the following error message:
#Error in dta[complete.cases(mf), names(dta) %in% vars, drop = FALSE] :
# incorrect number of dimensions
Any ideas on what I'm doing wrong?
Thanks
