Human Heredity, 2005
This note summarizes the development of the transmission/disequilibrium test (TDT). The initial purpose of the TDT procedure was to test for linkage between a genetic marker and a disease susceptibility locus when an association had been found between the two.

Risk significance and safety significance

Reliability Engineering & System Safety, 2001
Abstract Existing measures of the risk significance of elements of risk models (such as the Fussell–Vesely, or ‘F–V’, importance of basic events) are based on the properties of cut sets containing the element. A measure of safety significance (prevention worth, or PW ) is proposed, based on the properties of path sets containing the element.

The importance of significance and the significance of importance

Postgraduate Medicine, 1979
