Quantile-quantile plot for data vs fitted exponential distribution ------------------------------------------------------------
^qexp5^ varname [^if^ exp] [^in^ range] [ ^, m^ean^(^#^) gr^id graph_options ]
Description -----------
^qexp5^ plots the quantiles of varname against the quantiles of a one-parameter exponential distribution, with distribution function 1 - exp(-varname / mean). The values of varname should be zero or positive.
Note: this is the original version of ^qexp^, written for Stata 5. Users of Stata 8 up should switch to ^qexp^.
Options -------
^mean(^#^)^ specifies that the mean of the fitted distribution is to be #. If ^mean()^ is not specified the mean of the data set is used.
^grid^ adds grid lines at the .05, .10, .25, .50, .75, .90, and .95 quantiles.
graph_options are any of the options allowed with ^graph, twoway^; see help for ^graph^.
Examples --------
