An alternative discrete analogue of the half-logistic distribution

A discrete version of the continuous half-logistic distribution is introduced, which is based on the minimization of the Cram´er distance between the corresponding continuous and step-wise cumulative distribution functions. The expression of the probability mass function is derived in analytic form and some properties of the distribution are discussed, as well as sample estimation. A comparison is also made with a discrete version already proposed in the literature, which is based on a different rationale. An application to real data is finally presented.
