Research on Statistics

Abstract

Since ETS’s founding in 1947, staff members have made important contributions to both theoretical and applied statistics, especially in the areas of linear models, latent regression, Bayesian statistics and causal inference. Although much of this work was inspired by challenges arising in the course of operational activities, the developments often had broader implications, not only for the testing industry as a whole but also for general statistical practice. This chapter offers a comprehensive historical account of statistical research at ETS, with particular emphasis on those topics that are not covered in other chapters.
