A Bayesian analysis of the accumulated count of ozone exceedances in Mexico City
MetadataShow full item record
We consider the problem of understanding the behaviour of the mean number of times that a given environmental threshold is surpassed by a pollutant's concentration. We assume three parametric forms for that mean. All of them are, in one way or another, related to the mean of a non-homogeneous Poisson process. The parameters of the models will be estimated under a Bayesian point of view via Markov chain Monte Carlo (MCMC) methods. Results are applied to the daily maximum ozone measurements from the monitoring network of Mexico City. © 2013 Nova Science Publishers, Inc. All rights reserved.
