Dear All,
I desperately need help in choosing the most important features in my data set. I have 200 data and a label, Control=1 or not-control=2. So trying to find the best features which help me most in classifying this data set or the feature set that gives me the best classification accuracy. Please help me as I need to finish urgently.
Kind regards.

Not quite sure what your question. You can leave control as 1 and non-control as 2 (some fussy people like 0 and 1) just ensure when you identify your binary variables that you select first/last appropriately!
