BlandAltmananalyyseja, commonly known in the literature as the Bland-Altman analysis, is a statistical method used to assess agreement between two quantitative measurement techniques. It focuses on the differences between paired measurements rather than their correlation, to determine whether the methods can be used interchangeably. The method was introduced in 1983 by J. Martin Bland and Douglas G. Altman.
Typically, paired measurements x_i and y_i are collected for each subject. For each pair, compute the difference
Interpretation revolves around the magnitude of the bias and the width of the limits of agreement. Small
Limitations include reliance on normality of differences and the assumption of independent measurements. Bland-Altman analysis does
