Use of Zero-inflated model as prediction of maternal mortality in four states of Sudan

الملخص EN

This study aimed to test application of Zero-inflated model in prediction of maternal mortality in 4 states in Sudan, namely White Nile, Gedarif, North Kordofan and Centre Darfur States.

Results showed that using the bivariate intrinsic CAR specification for spatial random effects into zero-inflated models that already account for correlated count data slightly improved the fit, and that this is more pronounced when using the Poisson distribution, a surprising result based on our findings from where the Negative binomial distribution outperformed the Poisson distribution for any considered extension.
