The cutting process is in control, and you decide to check whether the process distribution is normal. The following statements create a Q-Q plot for DISTANCE, shown in Figure 10.1, with lower and ...

This example illustrates how you can use a normal Q-Q plot to estimate the capability index Cpk. The data used here are the distance measurements provided in the "Creating a Normal Quantile-Quantile ...

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 ...

The resulting graphical methods include normal quantile plots and related normal offset-function plots; and quantile and offset-function plots for comparison of two subpopulations. Confidence bounds ...
