理论上可靠性系数的最佳估计是根据两种测试形式的等价性的精确定义来表述的。参考有关测试的信息的若干完整性程度和特殊假设，推导了该理论公式的各种近似值。熟悉的斯皮尔曼-布朗公式被证明是可靠性问题一般公式的一个特例。为了比较的目的，给出了以各种方式计算的可靠性系数。
The theoretically best estimate of the reliability coefficient is stated in terms of a precise definition of the equivalence of two forms of a test. Various approximations to this theoretical formula are derived, with reference to several degrees of completeness of information about the test and to special assumptions. The familiar Spearman-Brown Formula is shown to be a special case of the general formulation of the problem of reliability. Reliability coefficients computed in various ways are presented for comparative purposes.
