Spatiotemporal models with confounding effects: application on under-five mortality across four sub-Saharan African countries by Haile Mekonnen Fenta, Haile Mekonnen Fenta, Ding-Geng Chen, Ding-Geng Chen, Temesgen T. Zewotir, Najmeh Nakhaei Rad

“…However, when the number of time points and spatial areas is large and the areas are disconnected, fitting the model becomes computationally complex because of the high number of required parameters to be estimated. Therefore, the main aim of this study is to adopt a spatiotemporal dynamic model that includes the confounding effects between time, space, and their interactions with fixed covariates, with a special emphasis on U5M across disconnected sSA countries.MethodWe used nationally publicly representative Demographic and Health Survey (DHS) data for the period from 2000 to 2020. …”
