关于似然比序随机比较的一些结果

Some Results on Stochastic Comparison in Likelihood Ratio Order

研究了两组随机变量列之间似然比序的随机比较 ,得到的结果推广了 Shaked 和 Shan-thikumar( 1 994)中的 Theorem1 .C.1 9和 Theorem1 .C.2 0 .

It is established the conditions to ensure the stochastic comparison of the Likelihood ratio order between the groups of random variables. The results obtained in the paper generalize the some works developed by Shaked and Shanthikumar in a sence.
