Disturbance-informed national recruitment priors

Returns intercept priors for the recruitment model informed by national demographic-disturbance relationships (Johnson et al. 2020). The returned priors override b0_mu and b0_sd in bb_priors_recruitment(); all other prior parameters retain their defaults.

Usage

bb_priors_recruitment_national(anthro, fire_excl_anthro)

Arguments

anthro

A number between 0 and 100. Percent non-overlapping buffered anthropogenic disturbance.

fire_excl_anthro

A number between 0 and 100. Percent fire disturbance not overlapping with anthropogenic disturbance. anthro + fire_excl_anthro must not exceed 100.

Value

A named vector with elements b0_mu and b0_sd, suitable for passing to the priors argument of bb_fit_recruitment().

Details

Priors are looked up from a pre-computed table in the bbouNationalPriors package. Integer values of anthro and fire_excl_anthro are matched directly; non-integer values trigger a model run (slower).
