Example performance metrics

Source: R/pm.R
P_PNI50.Rd

Functions that evaluate return probabilities of outcomes from the simulations.

Usage

P_PNI50(SMSE, Ref = 0.5, Yrs = NULL)

P_PNI80(SMSE, Ref = 0.8, Yrs = NULL)

P_WILD50(SMSE, Ref = 0.5, Yrs = NULL)

P_SMSY85(SMSE, Ref = 0.85, Yrs = NULL)

P_SMSY80(SMSE, Ref = 0.85, Yrs = NULL)

P_Sgen100(SMSE, Ref = 1, Yrs = NULL)

Arguments

SMSE

SMSE object returned by salmonMSE()

Ref

Threshold for the performance metric, used to calculate the probability that the metric exceeds this value

Yrs

Numeric vector of length 2 to indicate the year range over which to summarize performance. If NULL, the performance is summarized over all projection years.

Value

A vector of probabilities corresponding to population

Details

  • P_PNI50 calculates the probability that PNI exceeds 0.50 (threshold for an integrated-transition population, Withler et al. 2018)

  • P_PNI80 calculates the probability that PNI exceeds 0.80 (threshold for an integrated-wild population, Withler et al. 2018)

  • P_WILD50 calculates the probability that at least 50 percent of natural spawners are wild

  • P_SMSY80 calculates the probability that NOS exceeds 0.80 SMSY

  • P_SMSY85 calculates the probability that NOS/SMSY exceeds 0.85 SMSY

  • P_Sgen100 calculates the probability that NOS exceeds Sgen
