If there are no failures in the data set, follow the steps below to conduct a Weibayes analysis assuming an imminent failure: Choose Stat > Reliability/Survival > Distribution Analysis (Right Censoring) > Parametric Distribution Analysis. The two-parameter Weibull has been the most popular distribution for modeling lifetime data. We propose a four-parameter gamma extended Weibull model, which generalizes the Weibull and extended Weibull distributions, among several other models. We obtain explicit expressions for the ordinary and incomplete moments, generating and quantile functions and mean deviations. This video was created for Penn State's course AERSP 880: Wind Turbine Systems, by Susan Stewart and the Department of Aerospace Engineering (http://www.aero To generate a random data element which follows a Weibull distribution with fixed alpha and beta values you can use the Real Statistics formula =WEIBULL_INV(RAND(),alpha,beta) Alternatively, you can use the Excel formula 2012-09-25 · This same data set can be entered into a Weibull++ standard data sheet.

Let t i where i = 1,, n, be the dataset of n moments of failure or censoring.
Current usage also includes reliability and lifetime modeling. Frequently, you can model a set of data with more than one distribution, or with a distribution that has one, two, or three parameters.
