Let X1,…,Xnbe independent exponential random variables with respective hazard rates λ1,…,λn, and let Y1,…,Ynbe independent exponential random variables with common hazard rate λ. This paper proves that X2:n, the second order statistic of X1,…,Xn, is larger than Y2:n, the second order statistic of Y1,…,Yn, in terms of the likelihood ratio order if and only if with Λk=∑i=1nλik,k=1,2,3. Also, it is shown that X2:nis smaller than Y2:nin terms of the likelihood ratio order if and only if These results form nice extensions of those on the hazard rate order in Paˇltaˇnea [E. Paˇltaˇnea, On the comparison in hazard rate ordering of fail-safe systems, Journal of Statistical Planning and Inference 138 (2008) 1993–1997].
