几个对数正态总体共同均值的广义推断

Generalized inference for the common mean of several lognormal populations

Javad Behboodian, Ali Akbar Jafari

摘要:

研究了对数正态总体共同均值的假设检验和区间估计。基于广义p值和广义置信区间的概念,给出了两种方法。这些新方法是精确的,可以不受样本量、群体数量或差异假设的限制。仿真结果表明,新方法在覆盖概率、大小和功率等方面都优于现有方法。最后给出了一个实际医学数据的数值例子。

英文摘要:

A hypothesis testing and an interval estimation are studied for the common mean of several lognormal populations. Two methods are given based on the concept of generalized p-value and generalized confidence interval. These new methods are exact and can be used without restriction on sample sizes, number of populations, or difference hypotheses. A simulation study for coverage probability, size and power shown that the new methods are better than the existing methods. A numerical example is given with some real medical data.
