Figure 2: Q–Q (normal probability) plots compare the differences between two distributions by showing how their quantiles differ. ( a ) Probability plots for n = 40 noise samples and their box ...

Example 55.8: Creating PP and QQ Plots The following program creates probability-probability plots and quantile-quantile plots of the residuals (Output 55.8.1 and Output 55.8.2, respectively).An ...

A range of plots are available from the residual plots tab. The residuals can be standardised for probability plotting either singly or in pairs; their standard errors can be computed and plots with ...

The probability plot only requires a minimum of two data points. The software calculates the mean and standard deviation after entering P 10 and P 90 , or calculates P 10 and P 90 after entering P ...
