WebUse the residual plots to help you determine whether the model is adequate and meets the assumptions of the analysis. If the assumptions are not met, the model may not fit the … WebBoth the Residuals vs Fitted and the Scale-Location plots look like there are problems with the model, but we know there aren't any.

WebA residual plot is a graph that is used to examine the goodness-of-fit in regression and ANOVA. Examining residual plots helps you determine whether the ordinary least squares assumptions are being met. If these assumptions are satisfied, then ordinary least squares regression will produce unbiased coefficient estimates with the minimum variance. WebJul 21, 2024 · We can create a residual vs. fitted plot by using the plot_regress_exog() function from the statsmodels library: #define figure size fig = plt.figure(figsize=(12,8)) #produce regression plots fig = sm.graphics.plot_regress_exog(model, ' points ', fig=fig) Four plots are produced. The one in the top right corner is the residual vs. fitted plot. WebThe residual plot is below. The residuals by fitted value plot looks better. If it weren’t for a few pesky values in the very high range, it would be useable. If this approach had produced homoscedasticity, I would stick with this solution and not use the following methods.
