In this paper, A new distribution called Exponential Lomax distribution is introduced. It is seemed that the parameter values of our new distribution are depending on decreasing and upside-down bathtub failure rate function. Also, the statistical properties of this model are studied, such as, quantiles, moments, mean deviation. Moreover, maximum likelihood estimators of it ' s parameters are discussed. Finally, the procedure is illustrated by real data set. It is shown that the introduced model is more competitive than other models.

In this paper, a new distribution called Inverted Exponentiated Gamma (IEG) distribution is introduced. Also, the statistical properties of this model are studied, such as, quantiles, moments and moments of order statistics, maximum likelihood estimators of it's parameters are discussed. Moreover, an application of IEG distribution to a breaking strengths of glass …bres of length 1.5 cm data set is provided. Also, bivariate Inverted Exponentiated Gamma (BIEG) distribution is introduced as a MarshallOlkin type. Marginal and conditional distribution functions are studied Furthermore, joint hazard rate function and maximum likelihood estimates (MLEs) of the parameters are presented. An application of BIEG distribution to an UEFA Champion 0 s League data set is provided and the pro…les of the log-likelihood function of parameters of IEGD and BIEGD are ploted.

In this paper, a new distribution called New Generalized Extreme Value (NGEV) distribution is introduced. Also, the statistical properties of this model are studied, such as, quantiles, moment generating function and moments of order statistics. Moreover, maximum likelihood estimators of it's parameters are discussed.
