probit (plural probits)

   • 2002, chapter 5, in Behavioral Models‎^[1], UC Berkeley, page 101,119:

     The only limitation of probit models is that they require normal distributions for all unobserved components of utility. […] In the current section, I describe three simulators that are applicable for probits of any form: accept–reject, smoothed accept– reject, and GHK.

2. The probit function, the inverse of the standard normal cumulative distribution function.

• logit

From clipping of English probability.
