Zero-inflated Poisson from complex samples

This technical article explains how to add Zero-Inflated Poisson (ZIP) models to the R survey package for analyzing count data with excess zeros from complex survey samples. It includes a practical example using NHANES data on sexual partners, demonstrating code for model fitting and addressing design-based inference.
