The Odd Lindley-G Family of Distributions

Abstract

We propose a new generator of continuous distributions with one extra positive parameter called the odd Lindley-G family. Some special cases are presented. The new density function can be expressed as a linear combination of exponentiated densities based on the same baseline distribution. Various structural properties of the new family, which hold for any baseline model, are derived including explicit expressions for the quantile function, ordinary and incomplete moments, generating function, Rényi entropy, reliability, order statistics and their moments and k upper record values. We provide a Monte Carlo simulation study to evaluate the maximum likelihood estimates. We discuss estimation of the model parameters by maximum likelihood and provide an application to a real data set.

Bayesian Analysis of Weibull-Lindley Distribution Using Different Loss Functions

“…There are several standard probability distributions that have been used over the years for modelling real-life datasets however research has shown that most of these distributions do not adequately model some of these heavily skewed datasets and therefore creating a problem in statistical theory and applications. Recently, numerous extended or compound probability distributions have proposed in the literature for modeling real-life situations and these compound distributions are found to be skewed, flexible and more better in statistical modeling compared to their standard counterparts [1][2][3][4][5][6][7][8][9][10][11][12][13].…”

Properties and Applications of a Transmuted Power Gompertz Distribution

“…New families of distributions are produced day by day and are useful for adding parameters to all forms of probability distributions which makes the resulting distribution more flexible for modeling heavily skewed dataset. Some of these families of distributions include the beta generated family (Beta-G) [7], Transmuted family of distributions [8], Gamma-G (type 1) [9], the Kumaraswamy-G family [10], McDonald-G family [11], Gamma-G (type 2) family [12], Gamma-G (type 3) family [13], Log-gamma-G family [14], Exponentiated T-X family [15], Exponentiated-G (EG) family [16], Weibull-X family [17], Weibull-G family [18], Logistic-G family [19], Gamma-X family [20], a Lomax-G family [21], a new generalized Weibull-G family [22], a Beta Marshall-Olkin family of distributions [23], Logistic-X family [24], a new Weibull-G family [25], a Lindley-G family [26], a Gompertz-G family [27] and Odd Lindley-G family [28] and so on.…”
