d STB-19 dm18.  Trailing moving average extension to egen.
d STB insert by Sean Becketti, Stata Technical Bulletin.
d Support:  FAX  914-533-2902
d After installation, see help ^newegen^.  (Unfortunately, since egen 
d is an "official" part of Stata, the help for it is also official.
d newegen.hlp contains all the help for egen, including the new tma() 
d function.  You will just have to remember to type "help newegen" and 
d not "help egen", at least until Stata Corp. adopts tma() as part of the
d official ado-files.)
