Here's an example:
*** begin
clear*
sysuse auto
g x = log(price)/10
g new = (exp(lngamma(2))*exp(lngamma(1))/exp(lngamma(3)))*ibeta(2,1,x)
// alpha = 2, beta = 1
su new
*** end

To every ω-consistent recursive class κ of formulae there correspond
recursive class signs r, such that neither v Gen r nor Neg(v Gen r)
belongs to Flg(κ) (where v is the free variable of r).
