validate_fb4_inputs: Validate inputs for FB4 simulation

In fb4package: 'Fish Bioenergetics 4.0' Model Implementation with High-Performance 'TMB' Backend

Validate inputs for FB4 simulation

Description

Validates all inputs for FB4 simulation, including the Bioenergetic object and strategy-specific parameters.

Usage

validate_fb4_inputs(
  bio_obj,
  strategy,
  fit_to = NULL,
  fit_value = NULL,
  first_day = 1,
  last_day = NULL,
  observed_weights = NULL,
  covariates = NULL
)

Arguments

bio_obj	Bioenergetic object
strategy	Strategy to use: "binary_search", "optim", "bootstrap", "mle", "hierarchical"
fit_to	Fitting target (for traditional strategies)
fit_value	Fitting value (for traditional strategies)
first_day	First simulation day
last_day	Last simulation day
observed_weights	Vector of observed weights (for statistical strategies)
covariates	Covariates (for hierarchical strategy)

Value

Invisibly returns TRUE if all inputs are valid. Throws an error with a descriptive message at the first validation failure: invalid day range, unrecognised strategy, missing fit_to/fit_value for traditional strategies, or missing observed_weights for statistical strategies.

Examples

# Requires a fully-configured Bioenergetic object; see ?Bioenergetic
# validate_fb4_inputs(bio, strategy = "direct",
#                     fit_to = "Weight", fit_value = 200,
#                     first_day = 1, last_day = 365)
