How sensitive is the predictive distribution?

Unless otherwise noted, for every model and g. Unfortunately, it is not always possible to do Monte Carlo integration. Introduction to Probability and Statistics. Finally, I wish to express my sincere gratitude to Dale Poirier, for his constant support throughout kiop professional life, from teacher and PhD supervisor, to valued co-author and friend.

Our Bayesian reasoning says that we should summarize our uncertainty about what kooop do not know i. The numerical standard error does seem to give a good idea 4 We remind the reader that the computer programs for calculating the results in the empirical illustrations are available on the website associated with this book.

However, in general, we must bayesuan the computer to calculate 1. This means that empirical results can be presented using various priors. Here Monte Carlo inte- gration requires computer code which takes random draws from the multivariate t distribution.

That is, it uses the methods outlined in Section 3. All that you need to econometricx here is that the Gamma function is calculated by the type of software used for Bayesian analysis e.

However, another reason for discussing them is that they allowed us to introduce important methods 86 Bayesian Econometrics of computation in a familiar setting. The other equations above also emphasize the intuition that the Bayesian pos- terior combines data and prior information.

Hence, programs run at different times will yield different random draws. If the degree of correlation in your Gibbs draws is very high, it might take an enormous number of draws for the Gibbs sampler to move to the region of higher econimetrics probability. Shorthand notation for this is: You do not want a chain which always stays in regions of high posterior probability, you want it to visit areas of low probability as well but proportionately less of the time.

## Bayesian Econometrics

There are two main Bayesian strategies for sur- mounting such a criticism. Econometics distinguish the two models by adding subscripts to the variables and parameters.

The second computational method introduced is importance sampling. Since the denominator in 1. One measure of the magnitude of a matrix is its determinant.

In a model with autocorrelated errors see Chapter 6, Section 6. The use- fulness nayesian such probabilities is described in Section 3. A prior odds ratio of one is used.

In the previous chapter we introduced the intuition that one can interpret an MCMC algorithm as wandering over the posterior, taking most draws in areas of high posterior probability and proportionately fewer in areas of low posterior probability. With this choice, a Gibbs sampler can be set up which involves sequentially drawing from the Normal and Gamma distributions using 4. This reflects the intuitive notion that, in general, more information allows for more precise estimation.

Flowever, if the units of measure- ment of X 2 were changed to hundreds of square feet, then the interpretation would be based on a statement of the form: Throughout this book, we use bars under parameters e.

All results can be used to shed light on the question of fconometrics an individual regression coefficient is equal to zero. In this section, some of the discussion proceeds at a completely bayeslan level, with the prior simply denoted by p y,hand some of the discussion uses a prior which was noninformative for the linear regression model: The rest of this book can be thought of as simply examples of how 1.

In many empirical contexts, this may be a nice way of expressing the approximation error implicit in Monte Carlo integration. The importance sampling weights are then calculated as 4.
