Webull Corporation is an electronic trading platform owned by Hunan Fumi Information Technology, a Chinese holding company. [7] The platform offers low-cost trading of stocks , exchange traded funds (ETFs), options , margins , fixed income , and futures , with no platform fees. [ 8 ]
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.
For example,-the claim that Webull is owned by Fumi Technologies is not accurate, but it has been picked up by a number of lazy news sources that turn to Wikipedia for information. This erroneous claim references an old FINRA filing made by Webull Financial LLC (which is not even the subject of this article).
The Weibull modulus is a dimensionless parameter of the Weibull distribution.It represents the width of a probability density function (PDF) in which a higher modulus is a characteristic of a narrower distribution of values.
The q-Weibull is equivalent to the Weibull distribution when q = 1 and equivalent to the q-exponential when =. The q-Weibull is a generalization of the Weibull, as it extends this distribution to the cases of finite support (q < 1) and to include heavy-tailed distributions (+ +).
In probability theory and statistics, the generalized extreme value (GEV) distribution [2] is a family of continuous probability distributions developed within extreme value theory to combine the Gumbel, Fréchet and Weibull families also known as type I, II and III extreme value distributions.
The family of distributions accommodates unimodal, bathtub shaped* [1] and monotone failure rates.A similar distribution was introduced in 1984 by Zacks, called a Weibull-exponential distribution (Zacks 1984).
In probability theory and statistics, the discrete Weibull distribution is the discrete variant of the 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.
