Space–time dynamics regression models to assess variations of composite index for anthropometric failure across the administrative zones in Ethiopia

A single anthropometric index such as stunting, wasting, or underweight does not show the holistic picture of under-five children’s undernutrition status. To alleviate this problem, we adopted a multifaceted single index known as the composite index for anthropometric failure (CIAF). Using this undernutrition index, we investigated the disparities of Ethiopian under-fve children’s undernutrition status in space and time.
