or please propose me Another method for such a dataset (ISCX -2012) through which target course is categorical and all other characteristics are continual.
Really I used to be not able to know the output of chi^2 for feature selection. The situation has been solved now.
Recipes utilizes the Pima Indians onset of diabetes dataset to show the feature choice process (update: download from right here). This is a binary classification problem where all of the characteristics are numeric.
