  2. Weibull distribution - Wikipedia

    en.wikipedia.org/wiki/Weibull_distribution

    In probability theory and statistics, the Weibull distribution / ˈ w aɪ b ʊ l / is a continuous probability distribution. It models a broad range of random variables, largely in the nature of a time to failure or time between events. Examples are maximum one-day rainfalls and the time a user spends on a web page.

  3. Method of moments (statistics) - Wikipedia

    en.wikipedia.org/wiki/Method_of_moments_(statistics)

    An example application of the method of moments is to estimate polynomial probability density distributions. In this case, an approximating polynomial of order is defined on an interval [,]. The method of moments then yields a system of equations, whose solution involves the inversion of a Hankel matrix. [2]

  4. Estimating equations - Wikipedia

    en.wikipedia.org/wiki/Estimating_equations

    In statistics, the method of estimating equations is a way of specifying how the parameters of a statistical model should be estimated.This can be thought of as a generalisation of many classical methods—the method of moments, least squares, and maximum likelihood—as well as some recent methods like M-estimators.

  5. Discrete Weibull distribution - Wikipedia

    en.wikipedia.org/wiki/Discrete_Weibull_distribution

    The Discrete Weibull Distribution, first introduced by Toshio Nakagawa and Shunji Osaki, is a discrete analog of the continuous Weibull distribution, predominantly used in reliability engineering. It is particularly applicable for modeling failure data measured in discrete units like cycles or shocks.

  6. Exponentiated Weibull distribution - Wikipedia

    en.wikipedia.org/wiki/Exponentiated_Weibull...

    They showed that the exponentiated Weibull distribution has increasing, decreasing, bathtub, and unimodal hazard rates. The exponentiated exponential distribution proposed by Gupta and Kundu (1999, 2001) is a special case of the exponentiated Weibull family. Later, the moments of the EW distribution were derived by Choudhury (2005).

  7. Probability distribution fitting - Wikipedia

    en.wikipedia.org/wiki/Probability_distribution...

    An estimate of the uncertainty in the first and second case can be obtained with the binomial probability distribution using for example the probability of exceedance Pe (i.e. the chance that the event X is larger than a reference value Xr of X) and the probability of non-exceedance Pn (i.e. the chance that the event X is smaller than or equal ...

  9. Cumulant - Wikipedia

    en.wikipedia.org/wiki/Cumulant

    In the above moment-cumulant formula\ ⁡ = (:) for joint cumulants, one sums over all partitions of the set { 1, ..., n}. If instead, one sums only over the noncrossing partitions , then, by solving these formulae for the κ {\textstyle \kappa } in terms of the moments, one gets free cumulants rather than conventional cumulants treated above.
