Research on Statistical Procedures in Reliability Engineering.

Abstract

The 'time saved on life tests' by using extra items and not waiting until all items fail has been calculated for the exponential, Power-function, and Pareto distributions. The expected values for time ratios are calculated in 3 different ways and the results are quite different. For example, for 7 items tested to the first 3 failures, as compared to 3 items tested to 3 failures, the ratio of expected times is 0.28, whereas the expected ratio is 0.37 (with dependence) and is 0.44 (with independence).
