ppnCatchErr: Generate log-normal error associated with catch data
In TESA-workshops/TESAsamSim: Closed-loop salmon simulator for 2021 TESA workshop
Description

Examples
Description
Like the ppnAgeErr function, this function generates assigns multi-
variate logistic error (Schnute and Richards 1995, eqns.S.9 and S.10) to
proportions data. Here it is intended to represent error in assigning mixed
stock catches to specific stocks.
Usage
1
ppnCatchErr(ppnCatchVec, tau)
Arguments
ppnCatchVec
A numeric vector of proportions representing the true
relative contribution of each stock to total catch. nStocks =
length(ppnAgeVec).
tau
A numeric specifying the parameter that represents average var-
iation in proportions.
Value
Returns a numeric vector representing proportions for each stock.
Examples
1
2
3
ppnCatchVec <- c(0.2, 0.4, 0.3, 0.1)
tau <- 0.7
ppnCatchErr(ppnCatchVec, tau)
