Linear-exponential distribution


Author(s): Binod Kumar Sah

Abstract: In this paper, we introduce a new member of a family of continuous probability distribution which is based on the product of linear and exponential functions and hence, we named it ‘Linear-Exponential distribution’. Probability density function, probability distribution function and moment generating function of this distribution have been obtained. Moments about origin and hence, the first four central moments of the proposed distribution have been derived. The hazard rate function and the mean residual life function of the proposed distribution have been discussed, and show its flexibility over Lindley distribution. Estimation of parameters has been discussed by the method of moments as well as the method of maximum likelihood. Goodness of fit has been applied to different data-sets which were used by others and it has been observed that it gives better fit to the most of data-sets of same nature, having variance greater than the mean, than Lindley distribution.
