Reliability weibull
WebThe Weibull distribution (usually sufficient in reliability engineering) is a special case of the three parameter exponentiated Weibull distribution where the additional exponent equals 1. The exponentiated Weibull distribution accommodates unimodal, bathtub shaped [27] and monotone failure rates . WebT1 - An example on estimating Weibull scale (eta) and shape (beta) parameters from sample failure data. AU - Shailesh, K. R. PY - 2024/9. Y1 - 2024/9. N2 - In this paper a example is discussed to obtain the shape and scale parameters of Weibull distribution. Parameters are estimated using sample time-to-failure data or lifetime data.
