Abstract : A paper was presented at the previous Conference on the Design of Experiments about estimating the variance of the loss exchange ratio (LER). The LER is a measure of force effectiveness that is often used in military analysis of combat. Two methods of estimation were discussed: the method of error propagation, and the application of Fieller's theorem. The discussion that followed the presentation and further references to the literature pointed to Fieller's method as the preferred methodology to use to estimate confidence intervals about this measure of force effectiveness. Professor Bradley Efron presented an overview of bootstrap methods. Dutoit and Shannahan have applied bootstrap methods to data to compute an estimate of the LER. Confidence intervals were also determined. The distribution of LERs about the mean value derived from the bootstrap have been compared to results using error propagation and Fieller's theorem. The results of this comparison as well as the bootstrap sensitivity to different replication sizes are presented. (Author)
