Estimation of parameter of generalized exponential distribution (gexp) is obtained
based on generalized order statistics. The maximum likelihood and Bayes methods are
used for this purpose. Survival function and hazard rate are also computed. Estimation
based on upper record values from generalized exponential distribution is obtained as a
special case and compared by simulated data.
