Abstract: In this study, a Size Biased Exponential Distribution (SBEPD) is introduced and its moments are obtained. A size biased exponential distribution; a particular case of the weighted exponential distribution, taking the weights as the variate values has been defined. The estimates of the parameters of Size Biased Exponential Distribution (SBEPD) are obtained by employing the method of moments, maximum likelihood estimator and Bayesian estimation. Also, a Bayes’ estimator of Size Biased Exponential Distribution (SBEPD) has been obtained by using non-informative and gamma prior distributions.
