A new two-parameter power Lindley distribution is introduced and its properties are discussed. These include the shapes of the density and hazard rate functions, themoments, skewness and kurtosisâ€¦ (More)

This paper deals with the estimation of the stress-strength parameter R = P (Y < X) when X and Y are independent Lindley random variables with different shape parameters. The uniformly minimumâ€¦ (More)

A two-parameter weighted Lindley distribution is proposed for modeling survival data. The proposed distribution has the property that the hazard rate (mean residual life) function exhibits bathtubâ€¦ (More)

Although the literature on univariate count regression models allowing for overdispersion is huge, there are few multivariate count regression models allowing for correlation and overdiseprsion. Theâ€¦ (More)

This paper deals with the estimation of the stress-strength parameter R = P (Y < X), when X and Y are two independent weighted Lindley random variables with a common shape parameter. The MLEs can beâ€¦ (More)

In this paper,we are interested in the estimation of the reliability coefficient R = P(X > Y ), when the data on the minimum of two exponential samples, with random sample size, are available. Theâ€¦ (More)

In this paper, we derive the distribution of life length of a parallel system with random number of components when the life distribution of each component follows a Weibull distribution and theâ€¦ (More)
