fit_fb4_optim: Fit FB4 model using optim()

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

Fit FB4 model using optim()

Description

Coordinates the optim-based fitting process for weight or consumption targets, then runs a final detailed simulation with the optimal p_value.

Usage

fit_fb4_optim(
  target_value,
  fit_type,
  processed_simulation_data,
  method = "Brent",
  oxycal = 13560,
  lower = 0.01,
  upper = 5,
  hessian = FALSE,
  verbose = FALSE
)

Arguments

target_value	Target value to fit
fit_type	Type of fitting ("weight" or "consumption")
processed_simulation_data	Complete processed simulation data
method	Optimization method, default "Brent"
oxycal	Oxycalorific coefficient (J/g O2), default 13560
lower	Lower bound for p_value search, default 0.01
upper	Upper bound for p_value search, default 5.0
hessian	Whether to compute Hessian for standard errors, default FALSE
verbose	Whether to show progress messages, default FALSE

Value

List with fitting results and final simulation
