Description Create a pp-plot with with a shaded simultaneous acceptance region and, optionally, lines for a point-wise region. It works by plotting the two cumulative distribution functions against each other; if they are similar, the data will appear to be nearly a straight line. Objects created with ggplot2 can also be extensively customized with To appreciate what a PP plot can do, here is the output for a dataset of the same size and a similar mean generated with a geometric distribution rather than a Poisson distribution: The P-P Plot of Normality Test The cumulative probability plots of residuals (P-P plot) Is used to judge whether the distribution of variables is consistent with a specified distribution.
