Normal probability plot PDF + CDF vs t-distribution plot. n>30 gives stable normal distribution (otherwise there is no linearity around 0 on the residual plot) Procedure: (1) Sort R-student Residuals (2) Plot against cummulative probabilityi/nor $ (i-0.5)/n$, for i=1,2,...n ...
Syntax plotResidualDistribution(resultsObj)Description plotResidualDistribution(resultsObj) shows the normal probability plot and the corresponding histogram of the residuals. Use the plot to check if the distribution of the residuals deviates from the normality. example...
9.6.2 Normal Probability Plot To investigate the normality assumption for the ϵi, the ti are ranked in order of magnitude and plotted in such a way that observations from a normal distribution lie roughly on a straight line. However, some experience is needed in interpreting such plots. Dan...
Residuals should follow the normal distribution if you plan to use the p-values andconfidence intervals.Use a QQ plot to check them! Other Potential Problems There are several other ways that explanatory information might make its way into your residuals: Another variable must not be correlated wi...
variable to the vertical-axis residual values. The scattered random points along the horizontal axis indicate that there is no pattern associated with the points, so it would seem that this model is capturing this data without systematic errors. Asking the question "What is aresidualplot?"...

Quantile-quantile plot Kernel density estimate The last three plots are in Statistics and Machine Learning Toolbox™. If you see that your standardized residuals have excess kurtosis (fatter tails) compared to a standard normal distribution, you can consider using a Student’stinnovation distribution...
