Dear All,

I occasionally find the function truish() mentioned in other people's code, such as here:
http://repec.org/bocode/h/htm.ado
here
http://repec.org/bocode/d/drany.ado
and other, mostly in codes of Elliott Lowy (as far as I can identify)

I believe truish() is not part of standard Stata:
Code:
. version 16.0

. mata truish(1)
                 <istmt>:  3499  truish() not found
r(3499);
Could anyone, please, identify where is this function defined?

Thank you, Sergiy
