This paper considers the design of life-test sampling plans based on failure-censored accelerated life tests. The lifetime distribution of products is assumed to be Weibull with a scale parameter that is a log linear function of a (possibly transformed) stress. Two levels of stress higher than...

Using exponential smoothing, with an alpha value of 0.3 and assuming the forecast for January is 26, what is the forecast for June? A. 22.14 B. 21.57 C. 23.00 D. 22.75 Explain how to interpret the expected value. A component failure rate is described by a Weibull distribution with alpha...
Parametric survival regression (Weibull Model)4 The principle of the parametric survival regression is to link the survival time of an individual to covariates using a specified probability distribution (generally Weibull distribution). The Weibull model is a well-recognised statistical technique for ...
Watari et al. (2001) calculated the return periods of large SXR flares, solar energetic particle events and magnetic storms using the Weibull distribution. Riley (2012) estimated the occurrence probabilities of extreme events such as hard X-ray solar flares, high-speed coronal mass ejections (CM...
where ε denotes the exponential distribution, LN the log-normal distribution and W the Weibull distribution.λ is the parameter of the exponential distribution.α1 and β1 are the parameters of the log-normal distribution.α2 and β2 are the parameters of the Weibull distribution....
The problems of the Optimal robust Bayes estimation of Scale-Parameter for the Two-parameter Weibull distribution under the Type-Ⅱ censoring Life Test are discussed using the Г-posterior expected loss as the criterion. 以Г-后验期望损失作为标准,研究了定数截尾试验下两参数W e ibu ll分布尺度参数...
