Not to reply to your question, but to point out that, in English, if a
word is spelled with all uppercase letters, those letters are initial
letters of  words in the original name.  Thus:
SAS = "Statistical Analysis System"
SPSS = "Statistical Package for the Social Sciences"
SUDAAN = "SUrvey DAta ANalysis"
UNESCO = "United Nations Educational, Scientific and Cultural Organization"

"Stata" does not stand for anything else, and should never be spelled  "STATA".

Regards,

Steve
