How to integrate discrete variable in general linear regression model ?
显示 更早的评论
We have a data base of 18 continuous variables, 2 discrete variables and one dependant variable Y. We were able to build a linear model based only on the continuous variables using functions like regress() and stepwise()! But we need to integrate the two discrete variables in the model! Is there a method or function on matlab or statistics toolbox that we can use to do such a task??
Y is a 310*1 matrix and so are all the other variables!
Thank you!

I would suggest logistic regression for regression involving discrete variables. Or decission trees such as Fast and Frugal Trees
