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). Versions of Excel prior to Excel 2010 use the WEIBULLfunction instead of the WEIBULL.DIST function. 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? What is the mean time to failure?

Example of a Weibull distribution¶. Figure 3.19. This shows an example of a weibull distribution with various parameters. We’ll generate the distribution using:

The PDF value is 0.000123 and the CDF value is 0.08556. Functions for computing Weibull PDF values, CDF values, and for producing probability plots, are found in both Dataplot code and R code.

The two-parameter Weibull distribution is often used to characterize wind regimes because it has been found to provide a graphics_weibull-fitted- example.

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.

In the following example, a well-known software package was used. The Shape Parameter.

Typically will not know the Weibull distribution: α, β unknown. • Will only have sample data =⇒ estimates ̂ α,. ̂ β get estimated Weibull model for failure time 

We will then plot the PDF of the distribution.
