Summary

This chapter gives an overview of models to use in various method comparison situations, as well as explanations of the background and technical details about estimation procedures. If only one measurement by each method is available, the differences versus the averages is plotted, and whether the difference is constant and whether the variance of the difference is constant across the range of measurements, are checked. If replicate measurements are available for each method the differences should be plotted versus the averages. If more than two methods are compared, a person should decide whether they are so similar that it actually will make sense to compare them.
