Logistic判别参数的最大似然估计在小样本中显示出相当大的偏差，通过使用对数似然的高阶导数进行偏差校正的调整在模拟研究中被证明是有效的。该过程中说明了一个医疗诊断问题。
Maximum likelihood estimates of the parameters for logistic discrimination show considerable bias in small samples, Adjustment by a bias correction using higher derivatives of the log likelihood is shown to be effective in a simulation study. The procedure is illustrated in a medical diagnosis problem.
