SBT2: SBT complex MP

Description

An MP that makes incremental adjustments to TAC recommendations based on index levels relative to target levels (BMSY/B0) and catch levels relative to target levels (MSY)

Usage

SBT2(x, Data, reps = 100,
epsB=0.25,epsR=0.75,tauR=5,tauB=7,gamma=1)

Arguments

x

A position in a data-limited methods data object

Data

A data-limited methods data object

reps

The number of samples of the TAC

epsB

Control parameter

epsR

Control parameter

tauR

Control parameter

tauB

Control parameter

gamma

Control parameter

Details

This isn't exactly the same as the proposed methods and is stochastic in this implementation. The method doesn't tend to work too well under many circumstances possibly due to the lack of 'tuning' that occurs in the real SBT assessment environment. You could try asking Rich Hillary at CSIRO about this approach.
