两臂老虎机问题中的优势比估计AI 解读

Asymptotically optimal sequential procedures are proposed for fixed width interval and for point estimation of the log odds ratio for two Bernoulli populations. The costs of observations can be different for the two populations and possibly dependent on the success probabilities. The interval estimation procedure is studied by simulation for two sampling cost structures of particular interest, namely when the goal is to minimize the total average sample size, and when the…

双臂指数临床试验中的序贯估计AI 解读

Asymptotically optimal sequential procedures are developed for point and interval estimation of the difference and ratio of the means of two exponential populations. This is done in a clinical trial setting in which the responses are exponentially distributed survival times and are subject to censoring. The usual situation in which observations are immediate is treated as a special case. Some simulation results are given for moderate sample sizes.
