exceedProbsAggregated(threshold, lg, lastonly=TRUE)
This function computes regional exceedance probabilities after MCMC has finished, it requires the information to have been dumped to disk, and to have been computed using the function lgcpPredictAggregated $$P[\exp(Y_{t_1:t_2})>k],$$ that is the probability that the relative risk exceeds threshold $k$. Note that it is possible to pass vectors of tresholds to the function, and the exceedance probabilities will be computed for each of these.
