In wStockhausen/tcsamFunctions: Functions related to the BSAI Tanner crab stock assessment (2015+)

Calculate a ascending normal selectivity function with "3" parameterization

Description

Function to calculate (and optionally plot the components of) an ascending normal selectivity function with "3" parameterization.

Usage

selFcn.AscNormal3(zBs, params, fsZ, showPlot = TRUE)

Arguments

zBs	: vector of sizes at which to compute values
params	: vector of parameters
fsZ	: max possible size at which selectivity reaches 1
showPlot	: flag (T/F) to plot components of function

Details

Should replicate TCSAM02 ascnormal3 selectivity function.

params are:
1: delta size from max possible (params[4])
2: ln-scale selectivity at size givens by params[3]
3: size at selectivity is given by params[2]
4: max possible size at which peak is reached
