larkinParameters: Posterior estimates of Ricker stock recruit parameters
In TESA-workshops/TESAsamSim: Closed-loop salmon simulator for 2021 TESA workshop

Description Usage Format Source

A dataset containing posterior estimates of stock recruit parameters for CU- specific Larkin models fit to Fraser River sockeye salmon conservation units (CUs). Larkin models are extensions of Ricker models that account for de- layed density dependent effects by incorporating additional beta parameters.

1	larkinParameters

A data frame with 19000 rows and 8 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 for spawners in current year
beta1: density dependence parameter for spawners one year prior
beta2: density dependence parameter for spawners two years priod
beta3: density dependence parameter for spawners three years prior
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
