For example, a raw moment of the Weibull distribution is simply another raw moment of the exponential distribution. For an exponential random variable with mean , the raw moments are (details can be found here): Figure 1: Weibull Density in R Plot. 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.

As the failure rate of the Weibull distribution can both decrease and increase, it is LIFETIME MODELLING Then there is just a straightforward calculation: ( λ

The Weibull Distribution is derived from Extreme Value theory. Thus, the Weibull distribution is a more general probability density function that includes other functions as special cases. You can compute probability, mean, variance, standard deviation, mode, median, and Shannon's entropy (information entropy) using the formulas below, or by plugging the parameters into the calculator above.

Like Weibull distribution, a three-parameter inverse Weibull distribution is introduced to study … The Weibull distribution, an extreme value distribution, is frequently used to model survival, reliability, wind speed, and other data. One reason for this is its exibility; it can mimic various distributions like the exponential or normal. The two-parameter Weibull has a shape One can describe a Weibull distribution using an average wind speed and a Weibull k value. The graph below shows five Weibull distributions, all with the same average wind speed of 6 m/s, but each with a different Weibull k value.
