本文研究了Freese（1960）精度检验和Reynolds（1984）提出的相关检验之间的关系，并推荐了一种三向判定规则，作为对通常采用的接受/拒绝判定规则的一种慎重的替代。进一步的替代品提出的形式的点和区间估计的误差分布的参数进行审查。分析和模拟了偏差校正对检验过程和估计量的影响。当样本量不太小时，预检验后的条件偏倚校正与无条件偏倚校正表现相当。当误差是非正态的，所有的测试和估计大大降低，问题变得严重的大样本量。For. Sci. 34（2）：302-320。
The relation between the Freese (1960) accuracy test and the related test proposed by Reynolds (1984) is examined and a three-way decision rule is recommended as a circumspect alternative to the accept/reject decision rule commonly employed. Further alternatives are proposed in the form of point and interval estimates for parameters of the error distribution under scrutiny. The effect of bias correction on the test procedures and estimators is analyzed and simulated. Conditional bias correction following a pretest is shown to behave equivalently to unconditional bias correction when sample size is not too small. When errors are nonnormal, all tests and estimators degrade considerably, and the problem becomes severe for large sample sizes. For. Sci. 34(2):302-320.
