abstract
This article surveys the procedures used for deriving detector transfer functions and normalizing probability densities for the statistical analysis technique known as the "matrix element method" in the context of high energy physics (HEP) data analysis. Common misconceptions about transfer functions and efficiencies are pointed out and clarified.
