Estimation methods of theree parameters discrete generalized exponential distribution

This article presents the estimation methods of three parameters Discrete Generalized Exponential distribution. The two-parameter generalized exponential distribution was introduced by Gupta and Kundu (1999). We present the three parameters discrete Generalized Exponential distribution is the sum of infinite probability function. Moment estimation, inverse integer moment estimation, moment generating function, maximum likelihood estimation and L-moment estimation are derived for this infinite probability function.
