Classifier options greyed out in Weka [closed]

Question

I have numeric data which has missing values. I want to classify the data using Naive Bayes Classifier in Weka but the option is grayed out. Please help.

Answer 1

If a classifier is grayed out, it means that it doesn't support the kind of task you want to do. This could be because of the type of features or because of the type of predictions you want to make.

In your case it could be that you're trying to predict a numeric instead of a categorical attribute.
