In this paper,under constant-stress accelerated life test,the parameter estimations on a popula-tion with generalized half-normal distribution were considered.Firstly,it was proved that the product life forms a geometric process when certain conditions of the stress and parameters of generalized half-normal distribution are satisfied.Secondly,the maximum likelihood estimations,asymptotic confidence interval and bootstrap confi-dence interval estimations of the parameters were proposed.Finally,the obtained estimation results were nu-merically simulated,which showed that the model parameter estimations and confidence interval estimations were valid.
