Abstract : In this memorandum, new estimators are derived for the shape parameters of a Weibull time-to-failure distribution, and a Gamma distribution. In each case, a numerical table is presented to determine these estimators. The approach to reliability analysis taken differs from the usual practice; instead of simultaneously estimating the various parameters of multi-parameter failure distributions, a marginal estimator is obtained for only one parameter of a two-parameter failure distribution. The results should interest statisticians, engineers, and others concerned with reliability measurement and analysis. (Author)
