The residual plot shown offers a good example of what a problem-free plot should look like. There are no odd fan or curved trends in the plot, the average of the residuals is zero, and the points are equally represented about the x-axis.

Residual plot: The residual plot shows the difference between the calculated and measured values of the dependent variable as function of the measured values. If the regression model represents the data correctly, the residuals should be randomly distributed around the line of err=0 with zero mean.

Example 1, using logP as dependent and Trec, logT and T2 as independent variables, employing multiple linear regression is used to show the various information presented in the regression report, graph and residual plot windows.

In fact, there should be positive and negative values for the residual or the fit is questionable. An Outliers will give a large deviation in one direction which must be balanced with many smaller deviations in the other direction.

Partial residual plot - Wikipedia, the free encyclopedia
In applied statistics, a partial residual plot is a graphical technique that attempts to show the relationship between a given independent variable and the response variable given that other indepen...

Generate a partial residual plot. ... Dataplot provides two forms for the partial residual plot. You can generate either a single partial residual plot or you can generate a matrix of partial residual plots (one plot for each independent variable in the model).
