WebWe check if each residual plot have a systematic pattern. 1) Here we see a pattern wherein the residuals depart from 0 in a systematic manner. The residuals are negative for small x values, positive for medium x values, then negative again. This is a pattern so this is a NON-LINEAR regression. 2) Here we see the plot seems to have no pattern at ... Webstatsmodels.regression.linear_model.OLSResults. Results class for for an OLS model.
