Is it possible to estimate ```predict_proba``` with ```coef_``` but without ```_dual_coef_``` and ```support_vectors_```? If so, is there some python scripts I could get [/inspiration from]?\r\n\r\nHere's a full example of my current setup: https://gist.github.com/kingjr/cdc853e09aae9dde537c\r\n"},"comment":{"url":"https://api.github.com/repos/scikit-learn/scikit-learn/issues/comments/100035342","html_url":"https://github.com/scikit-learn/scikit-learn/issues/4689#issuecomment-100035342","issue_url":"https://api.github.com/repos/scikit-learn/scikit-learn/issues/4689","id":100035342,"user":{"login":"kingjr","id":4881164,"avatar_url":"https://avatars.githubusercontent.com/u/4881164?v=3","gravatar_id":"","url":"https://api.github.com/users/kingjr","html_url":"https://github.com/kingjr","followers_url":"https://api.github.com/users/kingjr/followers","following_url":"https://api.github.com/users/kingjr/following{/other_user}","gists_url":"https://api.github.com/users/kingjr/gists{/gist_id}","starred_url":"https://api.github.com/users/kingjr/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/kingjr/subscriptions","organizations_url":"https://api.github.com/users/kingjr/orgs","repos_url":"https://api.github.com/users/kingjr/repos","events_url":"https://api.github.com/users/kingjr/events{/privacy}","received_events_url":"https://api.github.com/users/kingjr/received_events","type":"User","site_admin":false},"created_at":"2015-05-07T22:11:43Z","updated_at":"2015-05-07T22:11:43Z","body":"That's right, thanks."}}
