Abstract: 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. There are ...

Abstract: Complex mechanical products usually contain multiple failure modes. Mixed Weibull distribution is often used to analyze their reliability, and their parameter estimation is more complex than ...

In this paper an estimator of the location parameter of the Weibull distribution is proposed which is independent of its scale and shape parameters. Several properties of this estimator are ...

Here’s a way to calculate the reliability for designs with several subsystems. • Weibull plots fit a curve through data, not data to a predetermined distribution’s curve. • After evaluating subsystems ...

The following data are taken from Lawless (1982, p.193) and represent the number of days it took rats painted with a carcinogen to develop carcinoma. The last 2 observations are censored data from a ...

For each distribution, the baseline survival distribution function (S) and the probability density function(f) are listed for the additive random disturbance. These distributions apply when the log of ...

Afify et al. [The Weibull Fréchet distribution and its applications, J. Appl. Stat., 43 (2016), pp. 2608-2626] defined and studied a new four-parameter lifetime model called the Weibull Fréchet ...
