| Abstract: | A new stochastic order named transform order of generalized total time on test(GTTT order for short) is established.Relationship between the GTTT order and the usual TTT transform order are investigated. It is found that the implications are closely related to the IFR or DFR property of the referred life distribution G. Preservation of the generalized TTT transform order is also developed by taking the maxima and minima of i.i.d. components. |
