Hello there, I hope someone here can help me with a probably trivial problem. I want to use the Classification Learner App. I have a dataset with a numerical response (years) and a number of character variables as predictors or, if possible, a mix of numerical and character variables as predictors. It seems like the Classification Learner App doesn't recognize character variables and I can't the the app to import my predictor variables. Does anyone have a solution for this??

Cheers Niclas

Hi Niclas,

I was looking at the documentation page, and it mentions that the predictors cannot be of any type other than numeric. I was trying a few examples and it allows an import only with numeric data types. Here is the documentation link that explains the same:

http://www.mathworks.com/help/stats/select-data-and-validation-for-classification-problem.html

You may have to edit the predictors to be numeric, or maybe you could take in the numeric values of the character predictors.

Hope this helps!
