    摘要: Abstract—The parallel constant-stress accelerated degradation
    test (PCSADT) is a popular method used to assess the reliability
    of highly reliable products in a timely manner. Although the maximum likelihood (ML) method is commonly utilized to estimate
    the PCSADT parameters, the explicit forms of the ML estimators,
    and their corresponding Fisher information matrix are usually
    difficult to obtain. In this article, we propose a two-stage ML
    (TSML) estimation procedure for a time-transformed model. In
    the proposed procedure, all the TSML estimators not only have
    explicit expressions but also possess consistency and asymptotic
    normality. Hence, this method is tractable for reliability engineers.
    Furthermore, the TSML estimators can provide constructive information about the unknown accelerated relationship law. The
    proposed method is also applied to analyze light-emitting diode
    data and compare the performance of our estimation procedures
    with the ML method via simulations.
