Calculate age composition input sampled size (iss)

Source: R/comp_stats.R

Function to calculate age composition iss (harmonic mean of realized sample sizes) and add nominal sample size (the number of ages actually aged) and the number of sampled hauls to output. Will compute for regional or spatially-explicit cases (depending on whether survey_region is defined, see arguments below)

iss_age(rss_age, specimen_data, survey_region = NULL)

Arguments

rss_age

iterated age composition realized sample size

specimen_data

age-length specimen input dataframe

survey_region

overall region, i.e., goa, ai, ebs, nbs... If defined, will compute statistics for spatially-explicit results. (default = NULL)
