Marginalized two part model for analyzing multilevel semicontinuous medical costs in Iranian households.

ABSTRACT: Medical costs (MCs) represent a significant burden on household finances and often lead to economic challenges. This study analyzed the data of 8,993 Iranian households from 2021 collected by the Iranian Statistical Center. Using a marginalized two-part model (MTP) with lognormal and gamma distributions, the relationship between MCs and factors such as age, gender, education, and household characteristics was examined. A two-level structure was applied to account for heterogeneity across provinces, with analyzes performed using R software. The mean annual MC was $180 with high variability (SD = $324.39). The main determinants included family size, residence area, education level, and socioeconomic status. Single households and families with more students had lower MCs. Among the models eva
