WebbThe Residual-Leverage plot shows contours of equal Cook's distance, for values of cook.levels (by default 0.5 and 1) and omits cases with leverage one with a warning. If the leverages are constant (as is typically the case in a balanced aov situation) the plot uses factor level combinations instead of the leverages for the x-axis. WebbIn the residual by predicted plot, we see that the residuals are randomly scattered around the center line of zero, with no obvious non-random pattern. The normal quantile plot of the residuals gives us no reason to believe that the errors are not normally distributed.

How to Obtain Predicted Values and Residuals in Stata

WebbPlotting Residuals You can plot the residuals against the regressors by using the PROC SGPLOT. For example, the following statements plot the 2SLS residuals for the demand model against price, income, and price of substitutes: WebbOne consequence of treating the variables as continuous is that the residual plot can appear as a series of parallel lines, as your plot shows. This makes the typical pattern … WebbIf TRUE `partial residuals' are also displayed on the plot. Borrowing terminology from GLM, partial residuals for covariate X j are defined as fitted values corresponding to X j + residuals (from the actual fit). If there is a single covariate, the partial residuals correspond to observed data. griffith vpn
