Using Thorson et al. 2020, understand the relationship between input sample size (number of PSUs per year) and the effective sample size for length composition data. Is this relationship different for camera and research fishing? What does our minimum Neff (45) mean in terms of annual PSU samples? On average, how many individuals are sampled within a PSU? What does this translate to for aging data?
