In statistical machine translation, a researcher seeks to determine whether some innovation (e.g., a new feature, model, or inference algorithm) improves translation quality in comparison to a baseline system. To answer this question, he runs an experiment to evaluate the behavior of the two systems on held-out data. In this paper, we consider how to make such experiments more statistically reliable.

This is a survey of non-linear regression models, with an emphasis on the theory
of estimation and hypothesis testing rather than computation and applications,
although there will be some discussion of the last two topics. For a general
discussion of computation the reader is referred to Chapter 12 of this Handbook
by Quandt. My aim is to present the gist of major results; therefore, I will
sometimes omit proofs and less significant assumptions. For those, the reader
must consult the original sources....
