A new continuous distribution, so-called the beta log-logistic distribution, that extends the log-logistic distribution and some other distributions is proposed and studied. When both shape parameters are positive infinity, the Beta distribution degenerates to a point distribution at 0.5. In the Bugs language it is used as x ~ dburrX(alpha, lambda) Burr XII The Burr XII distribution is defined by the pdf where alpha and beta are shape parameters, Klugman et al. The Burr distribution is very similar (and is, in some cases, the same as) many other distributions such as: A compounded Weibull with a gamma distribution as its shape parameter. The Burr X distribution is defined by the pdf where alpha is a shape parameter and lambda is a scale parameter, Surles and Padgett (2005) . Beta Kumaraswamy Burr Type X Distribution and Its Properties. distribution. There are a few special cases for the parameterization of the Beta distribution. For the first time, the beta Burr III distribution is introduced as an important model for problems in several areas such as actuarial sciences, meteorology, economics, finance, environmental studies, survival analysis and reliability. The generalization method used is the logit of beta distribution. In the next section we present certain characterizations of Beta Burr XII (BBXII) distribution. e.g. In this Research, we will define and study a four-parameter beta-Burr type V distribution. have introduced beta Burr type XII (BBXII) distribution which has five parameters (4 shape and one scale), which is different model to BBX.The BBXII has sub-models such is beta Weibull, beta Log-Logistic, beta Pareto type II, and exponentiated Burr type XII it is different from BBX as we see later. The beta Burr type X distribution properties with application Faton Merovci1*, Mundher Abdullah Khaleel2, Noor Akma Ibrahim2,3 and Mahendran Shitan2,3 Background In recent years, Burr type X (BX) distribution was introduced by Burr (1942) and it has received much attention in the literatures. 2. For s = m¡1 and k = 1, it reduces to a new distribution referred to as the beta log-logistic (BLL) distribution. Umar Yusuf Madakia,b,, Mohd Rizam Abu Bakara,c, Laba Handiqued aDepartment of Mathematics, Faculty of Science, Universiti Putra Malaysia, Malaysia. The BX distribution â¦ the Beta- Burr XII (BBXII) distribution discussed by Paranaíba et al. (2004) . Characterizations In designing a stochastic model for a particular modeling problem, an investigator will be vitally For details about this distribution, see. Burr XII distribution. For b = 1, it becomes the exponentiated Burr XII (EBXII) distribution, which is also not known in the literature. Paranaíba et al. The gamma distribution, The J-shaped beta distribution, The loglogistic distribution, The lognormal distribution, The normal distribution. (2011) where it was concluded that application of the Beta-BXII 3 distribution indicated that it had provided a better fit than other statistical models used in lifetime data analysis, the Kumaraswamy -Burr XII distribution introduced Other Types of Burr â¦ This post discusses the raising of a Pareto distribution to a power, as a result generating Burr distribution and inverse Burr distribution. Many familiar and useful models can be generated in this fashion. Clearly, the BXII distribution is a particular case for a = b = 1.
