How to Plot a Weibull Distribution in R To plot the probability density function for a Weibull distribution in R, we can use the following functions: dweibull (x, shape, scale = 1) to create the probability density function. curve (function, from = NULL, to = NULL) to plot the probability density function. From a failure rate model viewpoint, the Weibull is a natural extension of the constant failure rate exponential model since the Weibull has a polynomial failure rate with exponent {\(\gamma - 1\)}. This makes all the failure rate curves shown in the following plot A Weibull plot of thermal cycle data for Alloy 2 and Alloy 4.

To determine whether the data do not follow a Weibull distribution, compare the p-value to the significance level. Usually, a significance level (denoted as α or alpha) of 0.05 works well. A significance level of 0.05 indicates a 5% risk of concluding that the data do not follow a Weibull distribution when they actually do follow a Weibull distribution.

Topics include the Weibull shape parameter (Weibull slope), probability plots, pdf plots, failure rate plots, the Weibull Scale parameter, and Weibull reliability metrics, such as the reliability function, failure rate, mean and median. 2016-06-13 Another advantage of Weibull analysis is that it provides a simple and useful graphical plot. The data plot is extremely important to the engineer and to the manager. The Weibull data plot is particularly informative as Weibull pointed out in his 1951 paper.

Because the Weibull plot starts at a minimum time value of one, if fractional time values less than 1.0 are being analyzed, such as a failure at 0.5 hours, all time values should first be scaled upward by converting to minutes (i.e., multiply all times by 60 minutes/hour). … For example, this plot shows a uniform distribution that has a lower endpoint of 2.5 and an upper endpoint of 7.5. Weibull Complete the following steps to enter the parameters for the Weibull distribution . Weibull Distribution Overview. The Weibull distribution is a two-parameter family of curves. This distribution is named for Waloddi Weibull, who offered it as an appropriate analytical tool for modeling the breaking strength of materials. Current usage also includes reliability and lifetime modeling.
