hi,

I am trying to do a logistic regression in matlab with the glmfit function but I got an error message which says

" B = glmfit(C, [Y ones(253,1)], 'binomial', 'link', 'logit')
Warning: X is ill conditioned, or the model is overparameterized, and
some coefficients are not identifiable. You should use caution
in making predictions.
> In glmfit at 237
Warning: Iteration limit reached. "

What should I do fot the iteration limit problem ?

Is there any other method to do a logistic regression except glmfit function ?

By the way both my response and predictors are binary variables.
