Dear Stata-listers,
I am using a logistic model for a binary dependent variable "y" and an
explanatory variable "waste3". It is a comparative study of multiple sites
and hence I am producing a logit model for each site.
For a few sites I get the message
xi: logit y i.waste3
"note: waste3 dropped due to collinearity".
For others the message changes to
xi: logit y i.waste3
"note: waste3 != 0 predicts failure perfectly".
Will it be fair to assume that the two situations are equivalent.
Many thanks for your help in advance.
Amani
