QENV: Stata module to generate quantile envelopes for quantile-quantile plots
Maarten L. Buis, Nicholas J. Cox · RePEc: Research Papers in Economics · 2012
This package contains programs that each generate two numeric variables for later plotting on a quantile-quantile plot that define an envelope of low and high expectations for each quantile given repeated sampling from a specified distribution with the same number of values and same parameter values as the data specified. The programs are helper programs designed for use with qplot, which must be installed separately. (Type findit qplot to get references and code sources.) The package includes qenvnormal and qenvgamma.
