What do you want, the median (subject title) or the mean (the
question)? The jacknife is not appropriate for the median. For the mean
you can use -mean-, and for the median you can use -centile-. If you
want to use a resampling method you can use -bootstrap-, which is
appropriate for both the mean and the median. See the example below and
the helpfiles of these commands:
*--------------------- begin example ------------------
sysuse auto, clear
mean mpg
centile mpg
bootstrap mean=r(mean) median=r(p50): sum mpg, detail
*---------------------- end example -------------------
(For more on how to use examples I sent to the Statalist, see
