Abstract: When a dataset from a non-negative random variable contains zero or very small observations, the folded-normal distribution (FND) can be an appropriate model for fitting the data. Such data ...

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 ...

Estimating the conditional quantiles of outcome variables of interest is frequent in many research areas, and quantile regression is foremost among the utilized methods. The coefficients of a quantile ...

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 ...
