On the Bias of Maximum Likelihood Estimation Following a Sequential Test
研究了序贯概率比检验和三角检验后最大似然估计的偏倚，提出一种减少偏倚的调整估计方法，并给出其标准误近似值，附有实例和优缺点讨论。
The bias of maximum likelihood estimates calculated at the end of a sequential procedure is investigated. For the two sequential designs considered in detail, the sequential probability ratio test and the triangular test, this bias is appreciable. A method of calculating an adjusted estimate with reduced bias is described, and an approximation to the standard error of the new estimate is provided. Examples of the implementation of the method are given, and its advantages and disadvantages relative to alternative approaches are discussed.
