Table 2 Results of the GAMs for the distribution of anchovy eggs in Korean waters: regular GAM (binomial with logit for the egg presence/absence and Gaussian with identity for the egg density) and quantile GAM (elf with identity at modelling the 0.10th, 0.50th, and 0.90th quantile) in total and 0.50th and 0.80th quantile (1985), 0.50th, 0.70th, and 0.90th quantile (2002) in April for the egg density (log10)
