A New Bivariate Class of Life Distributions
Abstract Some concepts of multivariate aging for exchangeable random variables have been considered i
The Transmuted Exponentiated Additive Weibull Distribution: Properties and Applications
A new generalization of the transmuted additive Weibull distribution is proposed by using the quadratic rank transmutation map, the so-called transmuted exponentiated additive Weibull distribution. It retains the characteristics of a good model. It is more flexible, being able to analyze more complex data; it includes twenty-seven sub-models as special cases and it is interpretable. Several mathematical properties of the new distribution as closed forms for ordinary and incomplete moments, quantiles, and moment generating function are presented, as well as the MLEs. The usefulness of the model is illustrated by using two real data sets
The Generalized Transmuted Weibull Distribution for Lifetime Data
A new lifetime model, which extends the Weibull distribution using the generalized transmuted-G family proposed by Nofal et al. (2016), called the generalized transmuted Weibull distribution is proposed and studied.
Various of its structural properties including ordinary and incomplete moments, quantile and generating functions, probability weighted moments, RØnyi and q-entropies and order statistics are derived. The maximum likelihood method is used to estimate the model parameters. The new
distribution is applied to two real data sets to illustrate its exibility. It can serve as an alternative model to other lifetime models available in the literature for modeling positive real data in many areas
New Characterizations of the Pareto Distribution
Characterization results have great importance in statistics and probability applications. Some characterizations of Pareto of the rst kind and Pareto of the second kind distributions are presented by using conditional expectation in terms of their failure (hazard) rate. We also provide two characterization theorems based on the rth truncated moments
Transmuted Complementary Weibull Geometric Distribution
This paper provides a new generalization of the complementary Weibull geometric distribution that introduced by Tojeiro et al. (2014), using the quadratic rank transmutation map studied by Shaw and Buckley (2007). The new distribution is referred to as transmuted complementary Weibull geometric distribution (TCWGD). The TCWG distribution includes as special cases the complementary Weibull geometric distribution (CWGD), complementary exponential geometric distribution(CEGD),Weibull distribution (WD) and exponential distribution (ED). Various structural properties of the new distribution including moments, quantiles, moment generating function and RØnyi entropy of the subject distribution are derived. We proposed the method of maximum likelihood for estimating the model parameters and obtain the observed information matrix. A real data set are used to compare the exibility of the transmuted version versus the complementary Weibull geometric distribution
Exponentiated Transmuted Generalized Raleigh Distribution: A New Four Parameter Rayleigh Distribution
This paper introduces a new four parameter Rayleigh distribution as a generalization of the transmuted generalized Rayleigh distribution introduced by Merovci (2014). The new distribution is referred to as exponentiated transmuted generalized Rayleigh distribution (ETGRD). Various structural properties of the new distribution including moments, quantiles, moment generating function and RØnyi entropy of the subject distribution are derived. We proposed the method of maximum likelihood for estimating the model parameters and obtain the observed information matrix. A two real data sets are used to compare the exibility of the new model versus its sub models
The Generalized Kumaraswamy-G Family of Distributions
We propose a new class of continuous distributions called the
generalized Kumaraswamy-G family which extends the Kumaraswamy-G family
defined by Cordeiro and de Castro {[}1]. Some special models of the new
family are provided. Some of its mathematical properties including
explicit expressions for the ordinary and incomplete moments, generating
function, Renyi entropy, order statistics and characterizations are
derived. The new location-scale regression model is introduced based on
the new generated distribution. The maximum likelihood is used for
estimating the model parameters. The flexibility of the generated family
is illustrated by means of two applications to real data sets. (C) 2019

The Transmuted Weibull Lomax Distribution: Properties and Application
A new five parameter model is proposed and stutied. The new distribution generalizes the Weibull Lomax distribution introduced by Tahir et al. (2015) and is referred to as transmuted Weibull Lomax (TWL) distribution. Various structural properties of the new model including ordinary and incomplete moments, quantiles, generating function, probability weighted moments, Rényi and q-entropies and order statistics are derived. We proposed the method of maximum likelihood for estimating the model parameters. The usefulness of the new model is illustrated through an application to a real data set
The Complementary Geometric Transmuted-G Family of Distributions: Model, Properties and Application
We introduce a new family of continuous distributions called the complementary geometric transmuted-G family, which extends the transmuted family proposed by Shaw and Buckley (2007). Some of its mathematical properties including explicit expressions for the ordinary and incomplete moments, quantile and generating functions, entropies, order statistics and probability weighted moments are derived. Two special models of the introduced family are discussed in detail. The maximum likelihood method is used for estimating the model parameters. The importance and flexibility of the new family are illustrated by means of two applications to real data sets. We provide some simulation results to assess the performance of the proposed model.WoSScopu
