Bland and Altman's limits of agreement have been used in many clinical research settings to assess agreement between two methods of measuring a quantitative trait. However, when the variances of the measurement errors of the two methods are different, limits of agreement can be misleading. MethodCompare is an R package that implements a new statistical methodology, developed by Taffé in 2016. MethodCompare produces three new plots, the "bias plot", the "precision plot", and the "comparison plot" to visually evaluate the performance of the new measurement method against the reference method. The method is illustrated on three simulated examples. Note that the Taffé method assumes that there are several measurements from reference standard and possibly as few as one measurement from the new method for each individual.
Bland 和 Altman 的协议界限在许多临床研究中被用来评估两种测量定量特征的方法之间的一致性。然而，当两种方法的测量误差方差不同时，协议界限可能会产生误导。MethodCompare 是一个 R 包，它实现了 Taffé 在 2016 年开发的一种新的统计方法。MethodCompare 生成了三个新的图，即“偏差图”、“精度图”和“比较图”，以直观地评估新测量方法相对于参考方法的性能。该方法在三个模拟示例中进行了说明。请注意，Taffé 方法假设对于每个个体，参考标准有多次测量，而新方法可能只有一次测量。
