Re: [Gretl-users] Threshold in Logit/Probit Models
Thank you Sven,
What does the $yhat mean actually?

Maybe this is redundant, but let me just add that the $yhat accessor
after logit contains the predicted probability, not a binary 0-1
outcome. So a user may map these probabilities to 0-1 with any threshold
she chooses.
(For example like: series y01 = ($yhat > 0.3))
cheers
