Edit this page.   Source: R/MizerParams-class.R

Takes the rates \(R_p\) of egg production and returns reduced, density-dependent rates \(R\) given as $$R = R_p \exp{- b R_p}$$

srrRicker(rdi, species_params)

Arguments

rdi

Vector of density independent egg production rates \(R_p\) for all species.
species_params

A species parameter dataframe. Must contain a column ricker_b holding the coefficients b.

Value

Vector of density-dependent larvae production rates.
