只能用R（或者matlab）原因是python的包给的结果不准记得当时对比了一下，用sklearn regression跑出来的std error是不对的不知道这个bug现在fix了没有不过后来进入工业界也没人在乎std error这种差几个小数点的事情了作为科研工作者，我们经常需要进行繁琐的数据分析，并将分析结果进行可视化，以清晰地展示整体

Use predicted R-squared to determine how well a regression model makes predictions. This statistic helps you identify cases where the model provides a good fit for the existing data but isn’t as good at making predictions. However, even if you aren’t using your model to make predictions, ...

For feature selection, there are four statistical methods that we will talk about in this chapter: Aikake's Information Criterion (AIC), Mallow's Cp (Cp), Bayesian Information Criterion (BIC), and the adjusted R-squared. With the first three, the goal is to minimize the value of the ...
Ridge regression is one of the most popular shrinkage estimation methods for linear models. Ridge regression effectively estimates regression coefficients in the presence of high-dimensional regressors. Recently, a generalized ridge estimator was suggested that involved generalizing the uniform shrinkage of ...
