文中详细讨论了多个状态下二元正态分布均值和方差的无偏估计和置信区间估计。
Then it can establish the estimators of means and covariance matrix of the multivariate normal distribution, and estimate their confidence limits and intervals in each state.
用传统方法得到的两正态分布方差比的置信区间显然不是最短的，因而就此意义而言也不是最佳的。
The traditional method the confidence interval is not the shortest, so it is not the best one in this sence. Obtained the shortest confidence interval in theory.
