False Positive Rate (FPR) is a popular univariate statistical test for feature selection. We add a chiSquare Selector based on False Positive Rate (FPR) test in this PR, like it is implemented in scikit-learn. \r\nhttp://scikit-learn.org/stable/modules/feature_selection.html#univariate-feature-selection\r\n\r\n\r\n## How was this patch tested?\r\n\r\nAdd Scala ut\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/apache/spark/issues/comments/242087961","html_url":"https://github.com/apache/spark/pull/14597#issuecomment-242087961","issue_url":"https://api.github.com/repos/apache/spark/issues/14597","id":242087961,"user":{"login":"srowen","id":822522,"avatar_url":"https://avatars.githubusercontent.com/u/822522?v=3","gravatar_id":"","url":"https://api.github.com/users/srowen","html_url":"https://github.com/srowen","followers_url":"https://api.github.com/users/srowen/followers","following_url":"https://api.github.com/users/srowen/following{/other_user}","gists_url":"https://api.github.com/users/srowen/gists{/gist_id}","starred_url":"https://api.github.com/users/srowen/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/srowen/subscriptions","organizations_url":"https://api.github.com/users/srowen/orgs","repos_url":"https://api.github.com/users/srowen/repos","events_url":"https://api.github.com/users/srowen/events{/privacy}","received_events_url":"https://api.github.com/users/srowen/received_events","type":"User","site_admin":false},"created_at":"2016-08-24T14:39:04Z","updated_at":"2016-08-24T14:39:04Z","body":"OK, that looks solid for Scala.
