If the probability plot of residuals resembles a straight line, the residuals show a fairly good fit to the normal distribution.

Question

Quizplus · Accepted Answer

True, the probability plot of residuals is a graphical way to assess whether the residuals of a statistical model follow a normal distribution. If the plot looks like a straight line, it suggests that the residuals have a reasonably good fit to a normal distribution. If the plot is curved or nonlinear, it suggests that the residuals do not follow a normal distribution and may indicate a problem with the model.
