Reappraisal of Hypothesis Testing for Method Validation: Detection of Systematic Error by Comparing the Means of Two Methods or of Two Laboratories

The usual way of testing the equivalence of two measurement procedures is analyzed, and possible alternatives are discussed. It is shown that for method validation purposes, defining an interval of acceptable values and applying interval hypothesis tests is preferred over the usually applied point h...
