The first four raw and corrected moments of the predictive density for a single
future response are reported. The measures of skewness and kurtosis of a single future
response are given. The highest predictive density intervals for a single future response
are obtained based on several combinations of the hyperparameters. We reported the
summary results for the posterior model parameters and hyperparameters given the
simulated data and also the survival days of the leukemia patients. Furthermore, the
posterior kernel densities and dynamic trace for the parameters and hyperparameters
are graphically displayed. An advanced computational software package, ‘Mathematica
version 7.0’, was used to show the graphical representation of the predictive density for a
single future response and also to carry out all related calculations.
