Calculate Age-Frequency Likelihood (Version 1)

Usage

get_age_like_v1(
  af_year,
  af_fishery,
  af_min_age,
  af_max_age,
  af_obs,
  af_n,
  catch_pred_fya
)

Arguments

af_year: An integer vector, year indices for age-frequency observations.
af_fishery: An integer vector, fishery indices for observations.
af_min_age: An integer vector, minimum ages for aggregation.
af_max_age: An integer vector, maximum ages for aggregation.
af_obs: A numeric matrix of dimensions \[n_af, n_age\], observed age frequencies.
af_n: A numeric vector, sample sizes for each observation.
catch_pred_fya: A numeric array of dimensions \[n_fishery, n_year + 1, n_age\], predicted catch-at-age.

Value

A list containing:

pred: Predicted age frequencies (numeric matrix)
lp: Negative log-likelihood values (numeric vector)

Legacy status

These functions reproduce historical version-1 assessment code for audit and comparison. They are not the production SBT objective, do not implement the current data, mortality, harvest-wall, or biological-state contracts, and receive only compatibility maintenance. New analyses should use get_data(), sbt_model(), and the current component helpers.
