Map fishery catchability parameters

do_fish_q_mapping.Rd

Constructs the factor map for ln_fish_q, controlling whether catchability parameters are estimated independently per region and time block or shared across regions. Cells with no fishery index observations (UseFishIdx == 0) are automatically mapped to NA.

Usage

do_fish_q_mapping(input_list, fish_q_spec)

Arguments

input_list

Named list with $data, $par, and $map sublists.

fish_q_spec

Character vector of length n_fish_fleets. Options:

"est_all"

Separate catchability per region × block × fleet.

"est_shared_r"

Single catchability shared across regions, unique per block × fleet.

"fix"

All catchability parameters fixed (mapped to NA).

Value

The input input_list with $map$ln_fish_q set to a factor vector.
