Abstract

The objective of this paper is to estimate the group-based trajectory models for longitudinal infant mortality rate data of United Nations countries. Four linear trajectories were detected. The infant mortality rate has a descending trend over the period 1990–2010 for each of the trajectories. The time varying covariate variable Human Development Index has a strong statistically significant negative linear relationship with Infant Mortality Rate. The trajectory groups were correlated with the wealth classification of the nations.
