Hi all:
I have performed relogit with my variables successfully,
however, when I keep adding interaction items to see the moderation
effect, the error message occurs,
It says "matrix has missing values" whereas I am sure the interaction
variable has no missing value.
Does anyone know how to solve this problem?
p.s the two variables are both binary (0,1), thus the interaction term is
also binary
Thanks!

I'm new to R, so please excuse the question.
I have a large number of explanatory variables and R allows a shorthand of the form 'Y ~ .'
zelig gives an error when the model is "relogit":
Error in terms.formula(tmp, simplify = TRUE) :
'.' in formula and no 'data' argument
The full form of the command that I used is:
z.out <- zelig (Y ~ ., model="relogit", tau = NULL, robust = FALSE, data = d)
Any help is appreciated.
Best,
Lal
