Internal LBSPR Simulation Model

Description

A internal function that generates the expected equilbrium size composition given biological parameters, and fishing mortality and selectivity pattern. Typically only used by other functions in the package.

Usage

LBSPRsim_(LB_pars = NULL, Control = list(), verbose = TRUE, doCheck = TRUE)

Arguments

LB_pars

an object of class 'LB_pars' that contains the life history information

Control

a list of control options for the LBSPR model.

verbose

display messages?

doCheck

check if the LB_pars object is valid? Switch off when calling function from a optimization routine.

Details

The Control options are:

modtype

Model Type: either Growth-Type-Group Model (default: "GTG") or Age-Structured ("absel")

maxsd

Maximum number of standard deviations for length-at-age distribution (default is 2)

ngtg

Number of groups for the GTG model. Default is 13

P

Proportion of survival of initial cohort for maximum age for Age-Structured model. Default is 0.01

Nage

Number of pseudo-age classes in the Age Structured model. Default is 101

maxFM

Maximum value for F/M. Estimated values higher than this are trunctated to maxFM. Default is 4

Value

a object of class 'LB_obj'
