Web28 de set. de 2011 · We proposed a Bayesian hierarchical time series model for estimating U5MR and constructing short-term projections, as an alternative to the spline regression modeling approach. An autoregressive model for the annual rate of decline in U5MR captures changes more smoothly than a piece-wise linear regression model.
