glucose

74 persons in 5 centres in Finland had blood glucose measured by 11
different methods, based on 4 different types of blood. Each person had
blood sampled at 0, 30, 60 and 120 min after a 75 g glucose load.

datasets

Methods (standard and advanced) for analysis of agreement between measurement methods. These cover Bland-Altman plots, Deming regression, Lin's Total deviation index, and difference-on-average regression. See Carstensen B. (2010) "Comparing Clinical Measurement Methods: A Practical Guide (Statistics in Practice)" <doi:10.1002/9780470683019> for more information.
