Frustrated a little by the difficulty of running -clarify- with multiple
variables and many multiples of setx, particularly involving Stata's xi
prefix, I have written a wrapper for the clarify series that automates this
process.
The program and help files are available from Stata (thanks to Kit Baum) by
typing -ssc install qsim-
Title: QSIM
qsim provides a wrapper for the clarify series of program that automates
simulation , particularly with dummy variables produced by Stata's xi prefix.
Without qsim each of the 3 clarify programs has to be run separately for
each level of the xi: categorical variable. qsim can be placed into one or
more foreach loops and a large series of
simulations can be run at one time.
The output can be pasted into a text editor. Marking E( or Pr( identifies
the line with the simulation data output. This line then can be cut to
Excel (or similar programs) to make an output table. The whole process
takes less than a minute.
