Type _dtweedie	(	const double	y,
		Type &	mu,
		Type &	phi,
		Type &	p,
		bool	give_log
	)

dtweedie function (same as dtweedie.series from R package 'tweedie').

Silently returns NaN if not within the valid parameter range:

.

Note

Parameter order differs from the R version.

Warning

The derivative wrt. the y argument is disabled (zero). Hence the tweedie distribution can only be used for data (not random effects).

The dtweedie function was copied from TMB repository at https://github.com/kaskr/adcomp, then modified for ADMB data types.
