Dear Statausers,
I would like to know how I can save the bootstraped 95% confidence intervals
of a mean.
It would be best for me to save this either as a scalar or a local, since I
will be using these values to generate a special tabulation of several
variables.
Many thanks,
JP


bootstrap "summarize mpg, detail" r(mean), reps(1000)
