Bayesian methods for estimating dose response curves in quantal bioassay are studied. A linearized multi-stage model is assumed for the shape of the curves. A Gibbs sampling approach with data augmentation is employed to compute the Bayes estimates. In addition, estimation of the "relative additional risk" and the "risk specific…

Many factors influence the grades students earn. Without the intervention of institutional forces, it is reasonable to suspect that the mean semester index of successful students will remain constant with the passage of time.
