Get default parameter mapping

Gets the default parameter map used by RTMB::MakeADFun() to turn parameters on or off during optimization.

Usage

get_map(parameters)

Arguments

parameters

A named list containing the initial parameter values to be passed to MakeADFun.

Value

A named list of factor vectors. Elements mapped entirely to NA are fixed during optimization.

Details

The default map always fixes par_mc when it is present and fixes the three explicit concentration controls pop_od, hsp_od, and gt_od. It also fixes the configured assessment hyperparameters. Selectivity effects, including the current LL4 selectivity surface, remain estimated unless callers add them to the map.
