WebbSmall area estimators are split into two main types, depending on how models are applied to the data within the small areas: these two types are known as area level and unit level. Small area estimators are based on area level computations if models link small area means of interest (y) to area-specific auxiliary variables (such as x sample means).

WebbWith $mse, we can extract the estimated Mean Squared Error (MSE) of the EBLUPs. The MSE is estimated using a parametric bootstrap procedure. To make the bootstrap results reproducible, we set a seed. The MSE is an absolute measure. Often, relative measures give us a better picture of precision.

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.
