摘要
二分类总体单元被错误分类情形下,样本比例是总体比例的有偏估计。给出调整比例估计的两种方法:双样本方法和极大似然法,补充了经典抽样理论比例估计的内容。
Sample proportion is a biased estimate of population proportion p under binomial data with misclassification.Double sampling scheme and maximum likelihood method are proposed to adjust estimate of p that complement content of proportion in classic sampling theory.
