| 2], the inverted Gamma distribution IG (a, b), the conditional posterior distribution of [[sigma]. To determine the relationship between ambient levels and relative risk induced by our model, we examined the joint posterior distribution of average ambient levels, [[PSI]. Given the data observed, application of Bayes rule enables estimation of the posterior distribution of both the size and time of attack, from which summary statistics such as the mean, standard deviation, and probability intervals of the attack size and time are easily estimated. |
