Sampling errors in mortality and other statistics in life insurance.
Abstract The types, sources, and extent of data entering into the analytical statistics in life insurance companies are outlined. The statistical errors in mortality investigations arising as a result of the limited extent of the death claim experience or arising from the use of exposure sampling techniques are discussed. Comments are also made about the experience rating problem in group insurance and about a possible application of sequential analysis to the checking of files. * A paper presented at the 107th Annual Meeting of the American Statistical Association, New York City, December 30, 1947.
