Because it’s come up with so many ECON1620 students I’ve talked to this semester.
From the Stata FAQ:
4. The names Stata and Mata
4.1 What is the correct way to pronounce ‘Stata’?
Stata is an invented word. Some pronounce it with a long a as in day (Stay-ta); some pronounce it with a short a as in flat (Sta-ta); and some pronounce it with a long a as in ah (Stah-ta). The correct English pronunciation must remain a mystery, except that personnel of StataCorp use the first of these. Some other languages have stricter rules on pronunciation that will determine this issue for speakers of those languages. (Mata rhymes with Stata, naturally.)
4.2 What is the correct way to write ‘Stata’?
Stata is an invented word, not an acronym, and should not appear with all letters capitalized: please write “Stata”, not “STATA”. Mata is also an invented word, not an acronym.
