VitCap

Measurement on certain aspects of human lung capacity for 72 patients on 4
instrument-operative combination, i.e. two different instruments and two
different users, a skilled one and a new one.

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.
