Using Generalize​dLinearMod​el.stepwis​e

Has anybody else had trouble using this function? I am getting an error saying:

Undefined variable "GeneralizedLinearModel" or class "GeneralizedLinearModel.stepwise".

I am following the documentation correctly: http://www.mathworks.com/help/toolbox/stats/generalizedlinearmodel.stepwise.html

Here is my code: logit_step = GeneralizedLinearModel.stepwise(X_train,Y_train);

I have the statistics toolbox installed. I am able to use other functions like mnrfit.m. Any help would be appreciated.

What version of MATLAB are you using?

The statistical model classes were introduced in R2012a.
