Map recruitment regional apportionment parameters

Source: R/setup_recruitment.R
do_rec_region_prop_mapping.Rd

Builds the factor map for rec_region_prop_pars [n_pop x (n_regions - 1)], the logit-scale share of recruits per region, under a softmax with one reference region omitted. Both the parameter and its map are NULL when n_regions = 1. Called by Setup_Mod_Rec.

Usage

do_rec_region_prop_mapping(input_list, rec_region_prop_spec)

Arguments

input_list

Named list with $data, $par and $map. Requires $data$n_pop, $data$n_regions and $data$natal_region.

rec_region_prop_spec

Dispersal structure. "no_dispersal" assigns recruits entirely to their natal region, overwriting the starting values with -20 for non-natal regions and +20 for the natal region when natal_region > 1, and mapping every element to NA. NULL estimates all independently. Both require n_regions > 1.

Value

input_list with $map$rec_region_prop_pars set to a factor vector of length n_pop * (n_regions - 1), or NULL when n_regions = 1. Starting values are overwritten under "no_dispersal".
