Weibull verteilung

The Weibull distribution is one of the most widely used lifetime distributions in reliability engineering. In the last several issues of Reliability HotWire, we looked at how distributions are defined and how common reliability metrics are derived. Named for its inventor, Waloddi Weibull , this . The case where μ = and α = is called the standard Weibull distribution.

The equation for the standard Weibull distribution reduces to.

Since the general form of probability functions can be expressed in terms of the standard distribution, all subsequent .

Bei geeigneter Wahl ihrer zwei Parameter ähnelt sie einer Normalverteilung, einer Exponentialverteilung oder anderen asymmetrischen Verteilungen.

Für die Modellierung der statistischen Verteilung von . It was originally proposed to quantify fatigue data, but it is also used in analysis of systems involving a weakest link. SEE ALSO: Extreme Value Distribution, Gumbel Distribution. Im allgemeinen sind die Schätzer nicht analytisch, so daß ihre Klein- Stichproben-Eigenschaften nur über . It has CDF and PDF and other key formulas given by: with the scale parameter (the Characteristic Life), (gamma) the Shape Parameter, and is the Gamma function with for integer.

The cumulative hazard function for the Weibull is the integral of the . File: Weibull Wahrscheinlichkeitsnetz. It should be used in place of this raster image when not inferior. If all the scatter points are close to the reference line , we can say that the dataset follows the Weibull distribution. After analysis, we can get parameter estimates, which can determine survival function and hazard function of Weibull distribution . SEE: Extreme Value Distribution. Wolfram Demonstrations Project .
