Bayesian Model Comparison and Validation
Models are the venue for much of the work of the economics profession. We use them to express, compare and evaluate alternative ways of addressing important questions. Applied econometricians are called upon to engage in these exercises using data and, often, formal methods whose properties are understood in decision-making contexts. This is true of work in other sciences as well. There is an e...
متن کاملBayesian Model Assessment and Comparison Using Cross-Validation Predictive Densities
In this work, we discuss practical methods for the assessment, comparison, and selection of complex hierarchical Bayesian models. A natural way to assess the goodness of the model is to estimate its future predictive capability by estimating expected utilities. Instead of just making a point estimate, it is important to obtain the distribution of the expected utility estimate because it describ...
متن کاملComparison of Estimates Using Record Statistics from Lomax Model: Bayesian and Non Bayesian Approaches
This paper address the problem of Bayesian estimation of the parameters, reliability and hazard function in the context of record statistics values from the two-parameter Lomax distribution. The ML and the Bayes estimates based on records are derived for the two unknown parameters and the survival time parameters, reliability and hazard functions. The Bayes estimates are obtained based on conju...

متن کاملAttenuation Model Comparison And Validation
The Advanced Communications Technology Satellite (ACTS) propagation experiment has yielded five years measurements of rain rates and attenuation at 20.185 GHz and 27.505 GHz in seven diverse climate regions throughout North America. Figure 1 shows the former locations of ACTS propagation terminals. In the pursuit of rain attenuation models, rain has generally been classified as stratiform, conv...
