Currently looking at some dataset summaries and saw that there are very few if any zero sets in the IPHC survey:

fit_iphc_nb2 <- readRDS("data/generated/iphc-nb2-sdmTMB_gfdata.rds")
dplyr::summarise(fit_iphc_nb2$data, n = n(), p = mean(N_it20 > 0), .by = year)

Presumably the zero sets got removed somewhere along the way?

I’m pretty sure that’s real. Right, @LindsayDavidson ?
