bprobgHsPL: Internal Function
Description
It provides the log-likelihood, gradient and observed information matrix for
penalized or unpenalized maximum likelihood optimization, when using power link functions. 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), and Frank. For the normal case only, the Fisher information is also available.
