I have this task at my university where we have to point variables (from given set of rules) which was the most important for creating the final result - e.g. whether the customer will or won't buy something. Anyway, the result is categorical - yes or no, 1 or 0. And we have about 200 variables - columns.
We have to use Data Mining techniques.
Can you help me with choosing the best model ? And pointing how do I do this? I'm a newbie and I could really use some help.
