Dear users,
In my psychometric test i have applied logistic regression on my data. My
data consists of 50 predictors (22 continuous and 28 categorical) plus a
binary response. 

Using glm(), stepAIC() i didn't get satisfactory result as misclassification
rate is too high. I think categorical variables are responsible for this
debacle. Some of them have more than 6 level (one has 10 level).

Please suggest some better regression model for this situation. If possible
you can suggest some article.

thanking you.

Tirtha
