Domains can be defined by regional, temporal, or demographic aspects, as well as combinations of these three. For example, we can define our domains of interest as the cross-combinations of 5 states X 5 age classes X 12 months (total of 300 domains).

Webb6 mars 2024 · When working with counts, having many zeros does not necessarily indicate zero inflation. I demonstrate this by simulating data from the negative binomial and generalized Poisson distributions. I then show one way to check if the data has excess zeros compared to the number of zeros expected based on the model. Webb14 juni 2024 · Small Area Estimation with Zero-Inflated Model (SAE-ZIP) is a model developed for Zero-Inflated data that can lead us to overdispersion situation. To handle this kind of situation, this model is created.
