Threshold observation of a lognormal regression
= Threshold observation of a lognormal regression
{title2=$\mu=\log c+\sigma\alpha,\quad\beta=\sigma\gamma$}
Observing only whether a lognormally modelled output exceeds a known threshold produces a probit link. The latent location and slope are recovered by multiplying the probit coefficients by the known Gaussian scale and adding the log threshold to the intercept.
