We describe an approach to evaluating the mean square error of a possibly biased estimatorθ1 , using confidence intervals of a corresponding unbiased estimatorθ^. This approach has the remarkable property of not requiring an estimate, implicit or explicit, of the bias of θ1—the method is indifferent to the bias/variance breakdown of θ1's mean square error. The method was developed to evaluate competing biased estimators which incorporate data from a large wage survey in producing estimates of wages based primarily on a small detailed wage survey.

Speaker Bio

Our speaker is Senior Mathematical Statistician in the Office of Survey Methods Research at the Bureau of Labor Statistics and a Fellow of the American Statistical Association. He has taught at Temple University, Tulane University, and Johns Hopkins, where he earlier received his Ph. D. in Biostatistics. He also taught for a period at St. John's College, “the Great Books School”. He has published many journal articles and is co-author of a book “Finite Population Sampling and Inference: A Prediction Approach”, which attempts to bring survey sampling into better alignment with mainstream statistical thought and practice.
