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...

Multiple Linear Regression | Python By: Rajesh P.S.Multiple Linear Regression (MLR) is an extension of Simple Linear Regression (SLR) that enables the assessment of the relationship between two or more explanatory variables and a single response variable. It accounts for the influence of multiple...
