Publisher: School of Statistics, Renmin University of China, Journal: Journal of Data Science, Title: The Determinants of Birth Interval in Ahvaz-Iran - A Graphical Chain Modelling Approach, Authors: Abdolrahman Rasekh, Majid Momtaz

Highlights

  • Event histories such as birth, pregnancy and marriage have been used by social scientists to study fertility behavior of women

  • Besides examining the direct association of each determinant on birth intervals, we examine the effects of socio-economic determinants on intermediate determinants to understand the pathways through which the socio-economic determinants affect the birth interval

  • Graphical models combine a statistical model with its representation as a graph, where the underlying key concepts are conditional and marginal independence between the variables incorporated in the analysis

Summary

Introduction

Event histories such as birth, pregnancy and marriage have been used by social scientists to study fertility behavior of women. Nair’s (1996) analysis of birth intervals suggested that a significant differential existed between Hindus and Muslims in Kerala for the first and the second intervals, but not for the third birth interval This suggests that religion is an important factor in the fertility behaviour of women in Asia. This article intends to explore several questions regarding the socioeconomic, demographic, cultural differential and health-related factors on birth intervals, of children in Ahvaz-Iran, using a graphical modelling approach. This approach provides an interpretable empirical description and illustrates explicitly the conditional independence structure between each pair of variables.
