Overview of Agreement Statistics for Continuous, Binary, and Ordinal Data
Abstract: This will be a general overview presentation with practical examples and without much statistical formulas. We will introduce the concepts of un-scaled and scaled agreement statistics based on the basic case between two raters with paired samples for continuous, binary, and ordinal data. We will then progress into more complex cases when we have multiple raters and each rater has multiple readings per sample. Here, we can assess intra-rater and inter-rater agreement, compare inter-rater deviation to intra-rater deviation, and compare precision of a rater against another. We will explore the meaning of the two-stage criteria presented in the FDA guidance UCM070244: Statistical Approaches to Establishing Bioequivalence. The content is largely based on the materials presented in the newly published book by Springer, entitled "Statistical Tools for Assessing Agreement".
