Get log likelihood of age observations

Get log likelihood of age observations

Usage

getLogLik(pars, surveys, Delta_l = 1, Delta_t = 0.05)

Arguments

pars

A list containing the model parameters: k, L_inf, d, m.

surveys

A data frame with survey age-at-length observations with columns survey_date, Length, K, and count.

Delta_l

Width of size bins (cm). Default is 1.

Delta_t

Time step for the model simulation (years). Default is 0.05.

Value

A data frame with, for each observed Length-K bin in each survey, the observed count, expected count under the model, model probability, sample size, negative log-likelihood contribution, and signed negative log-likelihood contribution.
