Webb13 feb. 2024 · The offspring distribution describes not only the average number of new infections, but also the probability that any one infectious individual generated a large or small number of secondary cases. When the offspring distribution has a large right tail, the probability of superspreading events is high. Webb19 maj 2024 · This approach assumes that brood sex ratio results from a n-trials binomial distribution where n is the number of offspring, and therefore, it accounts for the fact that the variance in brood sex ratio depends on brood size, i.e. with smaller broods having larger random deviations from the mean than larger broods.
