MODELING THE PROPORTION OF NEONATAL MORTALITY
Amany Hassan Abdel-Karim
|
Abstract: Neonatal mortality proportion is the total number of neonatal deaths in a household out of the total number of under-five deaths. It is an indicator of living standard and health care for mothers and children. This proportion is restricted to the unit interval with nonzero probabilities of zero and one values. Adjusted three-part regression is a new model used to overcome the limitations of other regression models for analyzing proportional data. This model was applied to determine individual, household, and community effects on the household proportion of neonatal mortality using data extractedfrom Egypt Demographic and Health Survey. Variables significantly affecting neonatal mortality proportion are age of mother at first birth, total number of children ever born for a family, mother’s level of education, and household wealth index. |
Keywords and phrases: adjusted three-part regression model, Egypt Demographic and Health Survey, neonatal mortality, Newton-Raphson algorithm, proportional variable. |
