多参数单侧监测试验

Multi-parameter One-Sided Monitoring Test

Guangyu Zhu, Jiahua Chen

摘要:

多参数单侧假设检验问题在许多应用中自然出现。我们对监测林业产品多个质量指标的有效测试特别感兴趣。我们的搜索表明,在文献中有许多有效的统计方法用于正态数据,并且它们可以很容易地适用于非正态数据。我们发现,美丽的似然比检验是不令人满意的,因为为了控制大小,它必须应付最不利的分布在权力的代价。在本文中,我们找到了一种新的方法来稍微减轻大小控制,获得更强大的测试。仿真证实,新的测试保留了良好的控制I型错误,是明显更强大的比似然比检验以及许多竞争对手的基础上正常的数据。新方法在监测多个质量指标的情况下表现良好。

英文摘要:

Multi-parameter one-sided hypothesis test problems arise naturally in many applications. We are particularly interested in effective tests for monitoring multiple quality indices in forestry products. Our search reveals that there are many effective statistical methods in the literature for normal data, and that they can easily be adapted for non-normal data. We find that the beautiful likelihood ratio test is unsatisfactory, because in order to control the size, it must cope with the least favorable distributions at the cost of power. In this paper, we find a novel way to slightly ease the size control, obtaining a much more powerful test. Simulation confirms that the new test retains good control of the type I error and is markedly more powerful than the likelihood ratio test as well as many competitors based on normal data. The new method performs well in the context of monitoring multiple quality indices.
