Set up a legacy direct-anchor grid

Usage

get_grid(
  parameters,
  m0 = c(0.4, 0.45, 0.5),
  m10 = c(0.065, 0.085, 0.105),
  h = c(0.55, 0.63, 0.72, 0.8),
  psi = c(1.5, 1.75, 2L)
)

Arguments

parameters: A list containing the parameter inputs from which the grid will be created.
m0: Numeric vector of M0 (natural mortality at age 0) values to be included in the grid. Default is c(0.4, 0.45, 0.5).
m10: Numeric vector of M10 (natural mortality at age 10) values to be included in the grid. Default is c(0.065, 0.085, 0.105).
h: Numeric vector of steepness parameter values to be included in the grid. Default is c(0.55, 0.63, 0.72, 0.8).
psi: Numeric vector of reproductive-output power parameter values. Psi scales relative reproductive contribution by age. Default is c(1.5, 1.75, 2).

Value

A named list of parameter inputs, one per grid cell. Each element fixes par_log_psi, par_log_m0, par_log_m10, and par_log_h in a copy of parameters.

Details

This helper assumes the direct-anchor mortality parameterization and requires every grid vector to be nonempty. It is not suitable for the length-based mortality model without modification.

Legacy status

These helpers predate canonical portable sbt_fit grid cells and the current provenance and biological-state gates. They are retained for compatibility and exploratory work. Production posterior grids should use run_grid_mcmc() and grid_mcmc_to_tmbfit().
