Example set of performance statistics

Description

A set of performance statistics is provided, coded in the format that performance()requires. The statistics included in this list are as follows:

Format

An object of class list.

Details

• 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"
