Healthy Habits Restaurant, 4760 Baseline Rd. (Near Foothills Parkway) Abstract:
"Combining Information" offers numerous and challenging problems for
statisticians. I will discuss some of these. A variety of examples will be considered,
primarily from the Bayesian point of view. First, I will review approaches to the
estimation of physical constants. Next the problem of combining experimental results for
robust Bayesian testing of sharp null hypotheses is considered. Lower bounds on the
posterior probability of the null are obtained based on classes of priors. It is suggested
that plots of these lower bounds, as functions of the prior probability, provide a useful
summary of results for appraising evidence. An example involving the combination of
experiments concerning the value of aspirin usage for heart attack patients is presented.
The discussion includes comparison with classical p-values associated with meta-analysis.
Finally, time permitting, notions of combining information in large scale physical
modeling settings, such as those arising in Earth Sciences, are reviewed.
