RegressionResultsWrapper是statsmodels库中用于封装线性回归模型拟合结果的对象。当你使用statsmodels的OLS(普通最小二乘法)类进行线性回归分析并调用fit()方法后,就会得到一个RegressionResultsWrapper对象。这个对象包含了丰富的统计和模型信息,帮助你理解模型的拟合效果。 如何理解和使用RegressionResultsWrapper对象 解释Regressi...
To run that regression model in Python, you can use statsmodels’ formula API. It allows you to express linear models succinctly, using R-style formulas. For example, you can represent the preceding model with the formula 'watch_time ~ C(recommender)'. To estimate the model, just call the...

Seaborn regression plots 方便的是,Seaborn允许您直接进行其中一些绘图,而无需首先进行拟合的statsmodels。 这对于快速探索数据中的关系非常有用,并且令人高兴的是,这些图也比默认的Matplotlib图更漂亮。 有关示例和代码,请参见此处。 sns.lmplot('log_BodyWt', 'TotalSleep', data=sleep) ...
