Posterior estimates of Ricker stock recruit parameters

Description

A dataset containing posterior estimates of stock recruit parameters for CU- specific Ricker models fit to Fraser River sockeye salmon conservation units (CUs).

Usage

rickerParameters

Format

A data frame with 19000 rows and 5 variables:

stk

stock id, approximately equivalent to a conservation unit

alpha

productivity parameter (i.e. recruits per spawner at low spawner abundances)

beta0

density dependence parameter

sigma

standard deviation of normally distributed process error with mean = 0

deviance

estimate of model fit equivalent to residual sum of squares for linear models
