摘要
在非正态总体的条件下,给出的样本是小样本时,根据总体的不同情况,可以用确切概率计算法、Fisher正态近似法、切比雪夫不等式法等方法来确定总体未知参数的置信区间。
When the population is non-normal and the sample is a small one, we can use such methods as exact probability calculation, Fisher normal approximation and Chebyshev inequality to determine the confi- dence interval of unknown parameters according to the difference conditions of the population.
