A set of performance statistics is provided, coded in the format that
performance()
requires. The statistics included in this list are as
follows:
An object of class list.
SB0: Mean spawner biomass relative to unfished.
SBMSY: Mean spawnwer biomass relative to SBMSY.
Ftarget: Mean fishing mortality relative to target.
FMSY: Mean fishing mortality relative to FMSY.
green: Probability of being in Kobe green quadrant.
red: Probability of being in Kobe red quadrant.
PSBMSY: Probability of SB greater or equal to SBMSY.
PBlim: Probability that spawner biomass is above Blim.
risk1: ICES Risk 1, mean probability that spawner biomass is below Blim.
risk2: ICES Risk 2, probability that spawner biomass is above Blim once.
risk3: ICES Risk 3, max probability that spawner biomass is above Blim.
C: Mean catch over years.
VarC: Catch variability.
PC0: Probability of fishery shutdown.
Each indicator is itself a list object, with three elements, the first two of them compulsory:
An unnamed element of class formula, e.g. yearMeans(SB/SB0)
.
name: A short name to be output on tables and plots, of class character, e.g. "SB/SB0".
desc: A longer description of the indicator, of class character, e.g. "Mean spawner biomass relative to unfished"
