| Abstract: | The calculation of ratio bias of two expected lifetimes in the two-parameter exponential distribution is discussed under non-replacement fixed-number censored life time testing.The bound of the ratio bias and an approximate expression for the ratio bias are proposed.The results are supported by simulation studies. |
