Jul 21, 2020 · Residual Plots for Multiple Linear Regression. Suppose we instead fit a multiple linear regression model using assists and rebounds as the predictor variable and rating as the response variable: #fit multiple linear regression model model = ols ('rating ~ assists + rebounds', data=df).fit() #view model summary print (model.summary ()) Once again we can create a residual vs. predictor plot for each of the individual predictors using the plot_regress_exog () function from the statsmodels library.
Basically it computes the data predictions using the OLS parameters. Normally we need to analyze the residuals to check if our model is acceptable. A basic check is to look at the histogram of the residuals and plot a probability plot of the residuals. For details please refer to Q-Q plot.

The Statsmodels package provides different classes for linear regression, including OLS. However, linear regression is very simple and interpretative using the OLS module. We can perform regression using the sm.OLS class, where sm is alias for Statsmodels. OLS method. The sm.OLS method takes two array-like objects a and b as input.
