An MP that makes incremental adjustments to TAC recommendations based on the apparent trend in surplus production. Based on the theory of Mark Maunder (IATTC)
SPmod(x, Data, reps = 100, alp = c(0.8, 1.2), bet = c(0.8, 1.2))A position in data-limited methods data object
A data-limited methods data object
The number of quota samples
Condition for modifying the TAC (bounds on change in abundance)
Limits for how much the TAC can change among years
A numeric vector of TAC recommendations
Note that this isn't exactly what Mark has previously suggested and is stochastic in this implementation.
