It allows flexible modelling of both the counts at individual sites (required for the imputation) and of the population totals. 2. The models allow for covariates, hence seasonal effects resulting from multiple visits per site can be handled properly. 3. Several probability distributions (e. g. Poisson and negative binomial) are available.",
