摘要
在定量形态学中，如果采样单位不相等或以器官的特殊成分作为参考，则估计的形式为P = S yi/ S xi。令人感兴趣的是比值估计的偏差(P):异丙肾上腺素损伤后大鼠心室壁组织切片的体视学研究显示，在所有情况下，偏差都不重要。因此，没有必要使用无偏估计。
[Ratio estimate in medical morphometry (author's transl)].
In quantitative morphology the estimates have the form P = S yi/ S xi if the sampling units are unequal or a special constituent of the organ serves as reference. Of interest is the bias of the ratio estimate (P): the stereological investigation of tissue sections through the ventricular wall of hearts of rats following isoproterenol damage revealed that in all cases the bias is unimportant. Therefore it is not necessary to use unbiased estimates.
