I'd add the following nominees: 1. -stset-'. 2. -return list-. Or rather, all the good things stored in r(). 3. _n & _N, although they're not commands. Peter. -----Original Message----- From: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] On Behalf Of Nick Cox Sent: 21. maj 2004 15:02 To: statalist@hsphsun2.harvard.edu Subject: st: Top ten tricks [was: RE: RE: RE: RE: RE: RE: RE: Using postfile] Thanks very much. Being a bit smart with this stuff depends on smarter people having written it. The deeper lesson is the extraordinary leverage afforded by -by:-. That leads to me to ask a question: which would we nominate as (say) the top ten tricks which are the deepest and most Stataish features in what we use? What is _both_ simple _and_ deep? What leads to great results with at most a few lines of code? Let me explain what I mean. Something like -generate- is something utterly fundamental and extraordinarily useful and Stata could not be imagined without such a commnand. But the main idea is a standard one. The same could be said about say -if-. Commands like -regress- or -stcox- (no relation) are very well done, and key tools in the toolkit: but the greatness of the commands matches the greatness of the statistical idea and the associated machinery. On the other hand, -by:- still gives many pleasant surprises once you see how to use it. The more you use, the more you admire it. I'd nominate straight away 1. -by:-. 2. -foreach- or -forval- with varlists or numlists. 3. -merge-. I rarely use it but -merge-masters have real leverage in file manipulations. 4. -assert-. My candidate for the most underestimated command in Stata (second is -count-). 5. -reshape-. Any other nominations?
