A note on 'Parameter estimation for bivariate Weibull distribution using generalized moment method for reliability evaluation'

摘要

Yuan [Quality and Reliability Engineering International, 2018, doi: 10.1002/qre.2276] proposed a generalized moment method for parameter estimation of a particular bivariate Weibull distribution and derived corresponding confidence intervals. The expressions given for the confidence intervals do not appear correct. In this note, we correct the confidence intervals and recompute them for two real data sets.
