"The ultimate goal of this work is to provide a statistically rigorous approach to estimating the calibration factor for catches measured in numbers and total biomass. To this end, we first consider a suite of candidate calibration factor estimators and assess their statistical behavior through simulation. Some of these estimators, such as the quasi-likelihood estimator are previously considered in the literature (e.g., Pelletier 1998 and Lewy et al. 2004). For each species, we exclude some classes of estimators through tests of correlation of the paired tows at each station and tests of goodness-of-fit. We also evaluate statistical evidence for season-specific estimates of calibration factors"--Introduction.
