The characterization of the exponential distribution via the coefficient of the variation of the blocking time in a queueing system with an unreliable server, as given by Lin (1993), is improved by ...

Abstract: The exponential-exponential-weibull distribution (EEWD), a novel variation of the exponential weibull distribution, was developed and studied using the T-x method for merging distributions.

Abstract: In this paper, we introduce the notion of trace variance function which is the trace of the variance-covariance matrix. This trace variance function characterizes the Natural Exponential ...

Parameterizations for natural exponential families (NEF's) with quadratic variance functions (QVF's) are compared according to the nearness to normality of the likelihood and posterior distribution.
