WebMay 6, 2024 · For example, the residual of the first observation would be calculated as: Residual = 15 – 14.359 = 0.641. We can repeat this process for every observation in our dataset: Step 3: Create the Residual Plot. Lastly, we can create a residual plot by placing the x values along the x-axis and the residual values along the y-axis. WebInterpret the plot to determine if the plot is a good fit for a linear model. Step 1: Locate the residual = 0 line in the residual plot. The residuals are the {eq}y {/eq} values in residual …
