LSRA_opt: Internal estimation function for LSRA and LSRA2 functions

In DLMtool/DLMtool: Data-Limited Methods Toolkit

Description

Internal estimation function for LSRA and LSRA2 functions

Usage

LSRA_opt(
  param,
  FF_a,
  Chist,
  M_a,
  Mat_age_a,
  Wt_age_a,
  sel_a,
  Recdevs_a,
  h_a,
  Umax = 0.5,
  mode = 1
)

Arguments

param	a numeric value representing log(R0)
FF_a	numeric value, recent fishign mortality rate (apical F)
Chist	a vector of historical catch observations [nyears]
M_a	numeric value, natural mortality rate
Mat_age_a	a vector of maturity at age [nage]
Wt_age_a	a vector of weight at age [nage]
sel_a	a vector of selectivity at age [nage]
Recdevs_a	a vector of recruitment deviations [nyears]
h_a	a numeric value of steepness values of the Bev-Holt Stock-Recruitment relationship
Umax	maximum harvest rate per year
mode	1-5 see below

Value

depends on mode but could be 1:objective function 2:trajectory of Fs 3: SSB depletion 4:log(R0) 5:diagnostic plots
