An Investigation of a Statistical Procedure for Monitoring Two-Sample Life Tests.

Abstract

A statistical procedure is described for comparing two lifetime distributions when the data is reviewed repeatedly over time. The procedure provides the capability of early decision while maintaining both a fixed significance level and fixed maximum length for the entire experiment. The effects which staggered entry, number of looks at the data and maximum test length have on power and expected test length are discussed. An application is made to a bearing fatigue-life test.
