Description

A management procedure that makes incremental adjustments to TAC recommendations based on the apparent trend in recent surplus production. Based on the theory of Mark Maunder (IATTC)

Usage

1
2
SPslope(x, Data, reps = 100, yrsmth = 4, alp = c(0.9, 1.1), bet =
c(1.5, 0.9))

Arguments

x

A position in data-limited methods data object

Data

A data-limited methods data object

reps

The number of quota samples

yrsmth

Years over which to smooth recent estimates of surplus production

alp

Condition for modifying the Data (bounds on change in abundance)

bet

Limits for how much the Data can change among years

Details

Note that this isn't exactly what Mark has previously suggested and is stochastic in this implementation.

Value

A numeric vector of Data recommendations
