Hi!
Does somebody out there has experience with the Zelig package from Harvard uni?
I have a problem when trying to set the explanatory variables with setx
Polytomous logistic regression:>z.out <- zelig(OPARS ~ v1+v2+v3+...+vn, model = "mlogit",
data=heb)
that's OK>x.out<-set(z.out)
Error in seq.Date(along = object) : `from' must be specified
#??? I have no date objects present in the model???
Thanks
Anne
