INCORPORATING SAMPLING VARIATION AND RANDOM READER ERROR INTO CALCULATION OF EFFECTIVE SAMPLE SIZE IN THE APPLICATION OF AGE LENGTH KEYS TO ESTIMATION OF CATCH-AT-AGE PROPORTIONS
observations that contribute to the objective function via a multinomial likelihood. The multinomial likelihood ... an effective sample size (ESS) that can be used as the nominal multinomial sample size. The method ... accounts for both the variation associated with sub-sampling of the random length frequency (LF) sample for ... ageing, and random reader error when ageing fish.
