Small area estimation with excess zero

Webb31 dec. 2007 · Zero Inflated Negative Binomial (ZINB) method can be utilized to solve such problems. This paper demonstrates the adoption of ZINB methods in Small Area Estimation with excess zero data. It is shown that the excess zero problem has substantially influenced the Empirical Bayes (EB) estimates, and the adoption of ZINB … 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.

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. WebbThe other two small-area estimators are based on a model that takes zero inflation explicitly into account. Both the Bayesian and the frequentist approach are considered. …

WebbSmall area estimation (SAE) can be used for estimating U5MR in district/municipality level by using a mixed model. The model that is often used is generalized linear mixed model (GLMM). Direct estimation of U5MR produces a large proportion of zero values (excess zero), so the Poisson model is not suitable for modeling the data.
