The unit performance is a function of running time in years. The first step is to examine the distribution ID plot of the data and select the line that best fits our data. Look for the lowest Anderson-Darling normality value.

What is the mean time to failure? the Weibull distribution. Examples include life times affected by chemical corrosion, and the distribution of personal income. Keep in mind… To use the Weibull distribution requires knowledge of the scale and shape parameters, α and β, and there is a substantial literature on how to estimate these parameters from a given data set. Weibull Distribution Examples Median Rank Plot Example. In this example, we will determine the median rank value used for plotting the 6th failure from a sample size of 10.

Figure 1 illustrates the weibull density for a range of input values between -5 and 30 for a shape of 0.1 and a scale of 1. Example 2: Weibull Distribution Function (pweibull Function) In the second example, we’ll create the cumulative distribution function (CDF) of the weibull distribution.

Using information about the mean and variance of the original [Weibull] distribution we calculate the parameters of that resulting Normal distribution.

The distribution of a random variable that is defined as the minimum of several random variables, each having a different Weibull distribution, is a poly-Weibull distribution. The Weibull distribution was first applied by Rosin & Rammler (1933) to describe particle size distributions. Example 1: The time to failure of a very sensitive computer screen follows a Weibull distribution with α = 1,000 hours and β = .6. What is the probability that the screen will last more than 5,000 hours? For example, when β = 1, the pdf of the three-parameter Weibull reduces to that of the two-parameter exponential distribution. The parameter β is a pure number (i.e., it is dimensionless). The following figure shows the effect of different values of the shape parameter, β , on the shape of the pdf (while keeping γ constant).
