A Probit regression is a statistical method for a best-fit line between a binary [0/1] outcome variable \ (Y\) and any number of independent variables. Probit regressions follow a standard normal probability distribution and the predicted values are bounded between 0 and 1. For more information about Probit, see Wikipedia ...

WebThe problem with this model is that the cutpoint function is deterministic, and codes are observed. But in pymc (and in other MCMC programs, e.g. JAGS), a deterministic node cannot also be observed. So this model can't be built directly in pymc.
