WebBrief overview of residual plots. What one should look like for linear regression. A few examples of plots that indicate regression may not be your best bet. WebThe interpretation of a "residuals vs. predictor plot" is identical to that of a "residuals vs. fits plot." That is, a well-behaved plot will bounce randomly and form a roughly horizontal band around the residual = 0 line. And, no data points will stand out from the basic random pattern of the other residuals.

WebAnother way you could think about it is when you have a lot of residuals that are pretty far away from the x-axis in the residual plot, you'd also say, "This line isn't such a good fit." If you calculate the R value here, it would only be slightly positive, but it would not be close … WebInterpret the plot to determine if the plot is a good fit for a linear model.
