摘要
介绍了在小样本条件下3种构造对数正态分布均值置信区间的方法,即:PB方法,P值方法和r*方法。然后从4个方面进行对比,得出r*方法优于其它2种方法,并且在实际方面给予应用。
In this paper, we introduce three methods in the condition of small sample, which construct confidence intervals of the lognormal mean: PB method, P-value method and r^* method. We compare three methods which indicate r^* method is the best excellent than other two methods. At last, the result is applied by one example.
