" In the example below the median price of domestic cars is  4816"



-tabstat- yields a different result for the median price of domestic cars, though...


*************

sysuse auto, clear

qreg price foreign

//-tabstat- yields different result
tabstat price, stat(median)  /* 
*/ by(foreign) nototal /* 
*/ columns(variables)

Sounds like -qreg-. In the example below the median price
of domestic cars is  4816 and the price of foreign cars is
983 dollars higher, and this difference is significant.

*----- begin example -----
sysuse auto, clear
qreg price foreign
*------ end example -------
( For more on how to use examples I sent to statalist see:

Hope this helps,
