Statistics Seminars: Bayes linear kinematics in the analysis of failure rates and failure time distributions

Presented by Malcolm Farrow and Kevin Wilson, School of Mathematics & Statistics, Newcastle University

25 January 2010 14:15 in CM221

Collections of related Poisson or binomial counts arise, for example, from
numbers of failures in similar machines or neighbouring time periods. A
conventional Bayesian analysis requires a rather indirect prior
specification and intensive numerical methods for posterior evaluations.

An alternative approach using Bayes linear kinematics (Goldstein and Shaw,
2004) in which simple conjugate specifications for individual counts are
linked through a Bayes linear belief structure is presented. The use of
transformations of the binomial and Poisson parameters is proposed. The
approach is illustrated in two examples, one involving Poisson counts of
failures, the other involving binomial counts in an analysis of failure
times.
