How do you create a residual plot

WebA residual plot is a graph of the data’s independent variable values ( x) and the corresponding residual values. When a regression line (or curve) fits the data well, the residual plot has a relatively equal amount of points above and below the x -axis. Also, the points on the residual plot make no distinct pattern. WebJul 23, 2024 · Diagnostic Plot #2: Scale-Location Plot. This plot is used to check the assumption of equal variance (also called “homoscedasticity”) among the residuals in our regression model. If the red line is roughly horizontal across the plot, then the assumption of equal variance is likely met. In our example we can see that the red line isn’t ...
