Estimation of P(Y>X) with Measurements Subject to Error

Marie Coffin and Shashikala Sukhatme


Abstract

P(Y>X) can be estimated for data from any parametric family, although unbiased estimates are often not available for data from lifetime distributions, and the magnitude of bias in the estimate may be considerable. Also, if the variables are measured with error, the resulting estimates will be biased downward. Bias-corrected estimators are found for normal and exponential models, and simulation studies demonstrate that the bias-corrected estimators have MSE comparable to that of the uncorrected estimators.
