WebThe PP plot is a QQ plot of these transformed values against a uniform distribution. The PP plot goes through the points ( 0, 0) and ( 1, 1) and so is much less variable in the tails. Using the simulated data: Code Adding the … WebAug 20, 2007 · Quantile–quantile (Q–Q)-plots are a widely used graphical tool for comparing the distributional properties of a fitted statistical model against the empirical distribution of the data. The quantile scale acts to focus attention on the performance of the model at extreme levels, so Q – Q -plots are particularly appropriate for assessing ...
