The evaluation steps of aim-discovering rate for ess or lost index is introduced. Three kinds of typical index such as the aim-discovering rate, available incept distance of buoy signal and certain extension sensitivity progress emulated. The result shows that the method can improves the emulation precision. Keywords: Bootstrap meth
