Selectivity

Description

Calculate selectivity at age for Coleraine double-normal curve.

Usage

sel(Sfull, Sleft, Sright = 15, ages = 1:10)

Arguments

Sfull

age at full selectivity.

Sleft

a shape parameter for the left hand slope.

Sright

a shape parameter for the right hand slope.

ages

a vector of ages.

Value

Vector of selectivity values.

Note

The shape parameter for each slope is log variance. Use -15 for knife-edge and 15 for flat selectivity.
