Modeling on sequential r-out-of-n systems

Sequential order statistics, is an extension of the usualorder statistics and used for modeling lifetimes ofsequential r -out-of- n systems, coming from nonhomogeneous exponential distributions are considered.Via the likelihood approach, statistical proceduresincluding estimation, either point or interval, of theparameters as well as the generalized likelihood ratioare derived for testing homogeneity of the exponentialpopulations.
