Stepwise python
網頁2024年5月20日 · The Akaike information criterion (AIC) is a metric that is used to compare the fit of different regression models. It is calculated as: AIC = 2K – 2ln(L) where: K: The number of model parameters. The default value of K is 2, so a model with just one predictor variable will have a K value of 2+1 = 3. ln(L): The log-likelihood of the model. 網頁2024年6月25日 · ②pythonでstepwise regression用の関数を作っておく 本記事では、こちらの記事を主に参考にさせてもらいました。 ③pythonのstatsmodelsを使った重回帰分 …
