Table 4 Parameter estimates, 95 % Credible Intervals for Bayesian models considered

From: Understanding the determinants of under-five child mortality in Uganda including the estimation of unobserved household and community effects using both frequentist and Bayesian survival analysis approaches

 

Model IV: Weibull model

Model V: Bayesian Cox-PH model

Model VI: Bayesian (Weibull) model with community level frailty

Model VII: Bayesian (Weibull) model with household level frailty
