In this work, we present a five-parameter life time distribution called Harris power Lomax (HPL)  which is obtained by convoluting the Harris-G and Power distribution. When compared to existing distributions, new exhibits very flexible probability functions; may be increasing, decreasing, J, reversed J shapes been observed for density hazard rate functions. The structural properties of...

The concept of length-biased distribution is applied in expending proper models for lifetime data. The length-biased distribution is a special case of well-known weighted distribution. In this article, we introduce a length-biased weighted Lomax distribution (LBWLD) with k presence of outliers and estimate the parameter of R = P(Y < X) when the random variables X and Y are independent and have ...

This paper introduces a new three-parameter distribution which is obtained by combining the Lomax and Lindley distributions in serial system called Lomax-Lindley distribution. The quite flexible to model lifetime data. provides simple form for hazard rate function can be increasing, decreasing, bathtub-shaped unimodal different choices of parameter values. Some statistical properties such as qu...

istribution of Lindley distribution constructed by combining the cumulative function (cdf) Lomax and distributions. Some mathematical properties new are discussed including moments, quantile moment generating function. Estimation model parameters is carried out using maximum likelihood method. Finally, real data examples presented to illustrate usefulness applicability this distribution.

In this paper, the Weibull-Lomax distribution is considered for Bayesian analysis. The expressions Bayes estimators of parameter have been derived under squared error, precautionary, entropy, K-loss, and Al-Bayyati’s loss functions by using quasi gamma priors.
