# Cumulative Distribution Function The formula for the cumulative distribution function of the Weibull distribution is \( F(x) = 1 - e^{-(x^{\gamma})} \hspace{.3in} x \ge 0; \gamma > 0 \) The following is the plot of the Weibull cumulative distribution function with the same values of γ as the pdf plots above. Percent Point Function

In this issue, we will take a closer look at a specific distribution that is widely used in life data analysis - the Weibull distribution. Named for its inventor, Waloddi Weibull, this distribution is widely used in reliability engineering and elsewhere due to its versatility and relative simplicity.

Weibull distributions are characterised by a scale parameter, α, and a shape parameter, β (see Figure 1). There are also three-parameter Weibull distributions, which allow for different starting points; however, these are not elaborated on here. The key to understanding the behaviour of Weibull distributions is the shape parameter, and the hazard The modified (fixed‐shape) Weibull distribution can be used to faithfully describe the entire statistical distribution of the rms level of a journey or transport mode with just two parameters. This new approach can be used in a practical way for quantifying and comparing transport vibration rms levels for design and testing purposes. La distribution de Weibull est souvent utilisée dans le domaine de l'analyse de la durée de vie, grâce à sa flexibilité : comme dit précédemment, elle permet de représenter au moins approximativement une infinité de lois de probabilité.

It is named after Swedish mathematician Waloddi Weibull , who described it in detail in 1951, although it was first identified by Fréchet (1927) and first applied by Rosin & Rammler (1933) to describe a particle size distribution . The Weibull Distribution is a continuous probability distribution used to analyse life data, model failure times and access product reliability.
