import statsmodels.api as sm 下面我们引进这个包,来做我们的regression 首先决定好我们要找的因变量(dependent variable)和自变量(independent variable) Y = df[['price']] X = df[['height']] 如上代码块所示,那么下面就是开始regression 通过这串代码,我们可以得到一个OLS summary 好的那么现在要做的就是...

Least squares is one of the most-used techniques to build models because it’s simple and yields explainable models. In this example, you’ve seen how to use scipy.linalg to build such models. For more details on least squares models, take a look at Linear Regression in Python. Conclusion...
In this article, we discussed 7 effective ways to perform simple linear regression. Most of them are scalable to more generalized multi-variate and polynomial regression modeling too. We did not list the R² fit for these methods as all of them are very close to 1. ...
