The broad aim of a meta-analysis is to provide a review of the literature on some scientific question and to summarize the information in a quantitative manner. It is hoped that by reviewing all the available studies a stronger consensus view can emerge. Meta-analysis taken in this sense is more than statistics and involves a whole methodology for research synthesis.
The statistical part of such a review covers several aspects, of which the combination of the statistical evidence from several experiments is the most important one. It is fair to say that unless the statistical methods being used are sound, the numerical summaries from a meta-analysis may be misleading and no benefits may accrue from combining the studies.
We are developing new statistical techniques for meta-analysis and research synthesis with application to research synthesis in medical and actuarial sciences. Of particular interest are multivariate and sequential methods of meta-analysis in random effects model setting.
