DTe40(x, Data, reps = 100, plot = FALSE, alpha = 0.4, LB = 0.9, UB = 1.1)

DTe50(x, Data, reps = 100, plot = FALSE, alpha = 0.5, LB = 0.9, UB = 1.1)

Arguments

x

A position in the data object

Data

A data object

reps

The number of stochastic samples of the MP recommendation(s)

plot

Logical. Show the plot?

alpha

The target level of depletion

LB

The lowest permitted factor of previous fishing effort

UB

The highest permitted factor of previous fishing effort

Details

The TAE is calculated as:

\textrm{TAE}_y = \frac{D}{α} \textrm{TAE}_{y-1}

where D is estimated current level of depletion and α is argument alpha specifying the target level of depletion.

The maximum fractional change in TAE is specified with arguments LB and UB

Value

An object of class Rec with the TAE slot(s) populated
