sGenOptimum | R Documentation |
This is a component function within sGenSolver that estimates the log- likelihood of the relevant Ricker function.
sGenOptimum(S, theta, sMSY)
S |
A numeric of spawner abundances. |
theta |
A numeric vector of Ricker stock recruit parameters: alpha, beta, and sigma. |
sMSY |
A numeric of spawner abundance estimated to result in maximum sustainable yield. |
Returns a list of prt (estimated productivity), epsilon (the difference between sMSY and productivity), the negative log likelihood used to estimate sGen, and S.
