The classic method for assessment of reliable change, in 1991 re-introduced as Jacobson's RC, can be characterized as a confidence interval method. In recent years, several RC indices have been proposed using Kelley's (1947) (Kelley, T. L. (1947). Fundamentals of statistics. Cambridge: Harvard University Press) formula for estimating true change. In these proposals, interval estimation and confidence intervals are mixed up, which leads to unjustified probability statements. When Kelley's estimate is correctly expanded into a normal distributed statistic, the classic approach reveals itself as a large sample approximation of a properly constructed RCI based on Kelley's formula. Researchers should continue using the classic approach for the determination of reliable change.
1991年重新引入作为雅各布森可靠变化法的经典可靠变化评估方法，可被描述为一种置信区间方法。近年来，有人提出了几种使用凯利（1947年）（凯利，T. L.（1947年）。《统计学基础》。剑桥：哈佛大学出版社）估计真实变化公式的可靠变化指数。在这些提议中，区间估计和置信区间被混淆了，这导致了不合理的概率陈述。当凯利的估计正确扩展为正态分布统计量时，经典方法显示为基于凯利公式正确构建的可靠变化指数的大样本近似。研究人员应继续使用经典方法来确定可靠变化。
