WebA P–P plot (short for probability – probability plot or percent – percent plot) is a graph used to determine whether a given dataset fits a specific probability distribution. To test for normality using a normal P–P plot, you plot the cumulative probabilities of the rank of the values of the dataset against their corresponding probabilities of the values predicted by … WebThe Q-Q plot detects skew in the distribution of residuals. Q-Q plots and probability plots provide quick comparisons between probability distributions and can tell us how closely a data sample is to. A Q-Q plot or Quantile-Quantile plot is used to compare quantile distribution of a sample to a theoretical quantile distribution. Q-Q plot; P-P plot.

WebModel interpretation is a vital step after model fitting. For example, analysis of residual values helps to identify outliers; analysis of normal probability plots shows how “normal” the predictions were across the range of values for the dependent variable. For example, Fig. 7.15 shows a Statistica plot of partial residuals (residuals after effects of other …
