Estimation of effective sample size for catch-at-age and catch-at-length data using simulated data from the Dirichlet-multinomial distribution
year is important for such assessments, and this issue is studied using simulation. Between-haul ... heterogeneity within fishing year was simulated using samples from the Dirichlet-multinomial (D-M) distribution ... using aggregate year-level frequencies. The other three estimators use the haul-level frequencies ... on the new CV model; and (iii) that based on the PMLE. The year-level method gave very inaccurate estimates ... obtained from the integer values of year, y, so that for a 20-year simulation period y’ = y – 10 ... model A simulation model consisted of simulating 100 replications of a series of 20 fishing years ... from simu- lated sampling of the population age structure. For each of the 20 years in a replicate ... . For simulation Model 3, the selec- tivity parameter λ was varied linearly from 5.88 for the first year of the 20 ...
