The redundant factor method and bladder cancer mortality.

J C Barrett
PMCID: PMC1060969  PMID: 744823

Abstract

Of the three factors, age at death, epoch of death, and epoch of birth, one seems almost superfluous. It may nevertheless be worthwhile to include all three in a mortality analysis, allowing for the constraints that the redundancy imposes. This procedure is applied to data for England and Wales on bladder cancer mortality from 1951 to 1970.
