How to assess the agreement between two methods of measurement in Analyse-it. The tutorial covers:

  • plotting the relationship between the methods
  • estimating the average bias and the limits of agreement
  • why repeatability matters, and using replicate measurements
  • handling a difference that changes with the magnitude, including transforming the measurements to remove it
  • regression-based limits of agreement
  • non-parametric limits of agreement
