    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.
