llikNbinom

Calculate the log likelihood of the negative binomial function (and its derivatives)

Provides the log-likelihoods with gradients from 'stan'
(Carpenter et al (2015), <doi:10.48550/arXiv.1509.07164>) needed
for generalized log-likelihood estimation in 'nlmixr2'
(Fidler et al (2019) <doi:10.1002/psp4.12445>). This is
split of to reduce computational burden of recompiling 'rxode2'
(Wang, Hallow and James (2016) <doi:10.1002/psp4.12052>) which runs
the 'nlmixr2' models during estimation.
