Abstract: Abstract Along this paper, we study the relationship between the unimodality of the likelihood ratio and the behaviour of the ratio of two survival functions. The results provide sufficient conditions for both the hazard rated order when the likelihood ratio order does not hold and the mean residual life order when the hazard rate order does not hold. Examples where these results can be applied are also given.
