Note that there are two equivalent ways of presenting the classical approach. Firstly, the expected proportion of infected captured individuals is taken as a function of risk factors plus a random term based on a centered binomial distribution. Secondly, the probability that each captured individual is infected is taken as a function of risk factors, with random fluctuations in expected proportions naturally arising from these probabilities. Here, we present the second format because it allows us to easily illustrate how our approach is, in fact, a natural extension of the classical one.
