bprobgHsContSS: Internal Function
Description
It provides the log-likelihood, gradient and observed information matrix for
penalized or unpenalized maximum likelihood optimization in the case of non-random sample selection, when one
response is binary and the other continuous. Possible
bivariate distributions are
bivariate normal, Clayton, rotated Clayton (90 degrees), survival Clayton, rotated Clayton (270 degrees), Joe,
rotated Joe (90 degrees), survival Joe, rotated Joe (270 degrees), Gumbel, rotated Gumbel (90 degrees), survival Gumbel,
rotated Gumbel (270 degrees), Frank, FGM, AMH.
