Steve, Sorry about it! I have been in and out of the Statalist, but did not go through the FAQ carefully this time. I will certainly keep it in mind before my next post. Sincerely, Suryadipta.

Like most of us, I'm sure you just briefly scanned the FAQ when you joined, so it was easy to miss the contents of the last entry: that the proper way to write the name of our program is "Stata", not "STATA" The all-upper-case names of programs like SAS ("Statistical Analysis System") and SPSS ("Statistical Package for the Social Sciences") are acronyms: their letters stand for words in the original names. That's not true of Stata; hence it is spelled like a regular name, with only the first letter capitalized. > > > Steve > > > > On Sep 12, 2011, at 12:10 AM, Suryadipta Roy wrote > <<>> > > > Hello everyone, > I am a newbie in terms of writing STATA codes, and intend to get that > corrected pretty soon.
