摘要

The time to failure is modeled as a two-parameter Weibull distribution. Two estimates of the shape parameter are constructed: an estimate based on the first failures in each of the k identical test units, and an estimate based on the ratios of the second to the first failure times within each unit. The supposition is that these ratios will be shortened if the first failure has influenced the second. Numerical examples are also provided as illustration.
