Measurements of the distance between two holes cut into 50 steel sheets are saved as values of the variable DISTANCE in the following data set: data sheets; input distance @@; label distance='Hole ...

The following properties of Q-Q plots and probability plots make them useful diagnostics of how well a specified theoretical distribution fits a set of measurements: Q-Q plots are more convenient than ...

This paper discusses construction and interpretation of quantile plots using data obtained through a complex sample design. Previous quantile-plotting methods are extended through the use of ...

Quantile residual lifetime analysis is conducted to compare remaining lifetimes among groups for survival data. Evaluating residual lifetimes among groups after adjustment for covariates is often of ...
