In [[clinical measurement]] comparison of a new [[measurement]] technique with an established one is often needed to see whether they agree sufficiently for the new to replace the old. Such [[investigation]]s are often analysed inappropriately, notably by using [[correlation coefficient]]s. The use of correlation is misleading. Bland and Altman developed their analysis to address the inappropriate use of the correlation coefficient as a means of comparing 2 methods of measuring the same clinical [[parameter]]. However, a careful reading of their manuscript shows that the short-coming they sought to address was of mistaking a high degree of correlation for [[agreement]] (or concordance) between 2 measurement techniques. agreement.txt Last modified: 2024/06/07 02:55by 127.0.0.1
