There are user-written -egen- functions for row medians, 
but these are not appropriate for panel data. Kevin 
Crow has written a -egen- function for moving medians, 
but on the whole I guess that the tool closest to 
your needs is -mvsumm- from SSC, whose first author 
is Kit Baum. 

All this can be found out by using -findit- with 
key words.
