The plot compares the ordered values of DISTANCE with quantiles of the normal distribution. The linearity of the point pattern indicates that the measurements are normally distributed. Note that a ...

Q-Q plots are more convenient than probability plots for graphical estimation of the location and scale parameters since the x -axis of a Q-Q plot is scaled linearly. On the other hand, probability ...

A simple, nonparametric two-sample test for equality of a given collection of quantiles is developed which can be applied to a variety of empirical distribution functions, including the Kaplan-Meier ...

The normal quantile-quantile (Q-Q) plot of residuals is a popular diagnostic tool for ordinary linear regression with normal errors. However, for some generalized linear regression models, the ...
