摘要
普通统计分析方法是基于样本服从正态分布为前提,而实际样本很难满足正态分布的要求,易导致样本期望对离群值不稳健致分析结果失真及价值信息丢失。四分位稳健统计技术受极值影响较小,可以弥补普通统计方法的不足,但分析过程中要涉及到大量的数学运算。因此,为了克服稳健统计技术的缺陷,本研究设计特定程序及人机交互界面完成数学运算,使四分位稳健统计更加方便直观;同时对设计程序进行验证,结果表明其运行效果良好。
General statistical analysis methods are based on the premise of sample which is normal distribution,but actual samples are difficult to meet the requirements of normal distribution, and cause samples expectations of outliers are not robust to the results of the analysis distortion and loss of valuable information. It can make up for deficiency of the generals statistical method, duing to the fact that the four-piont robust statistical technique is not affected by the outlier date,but there is a lot of mathematics involved in the analysis. So in order to overcome these disadvantages, this study uses the computer programming program to complete the mathematical operation, and makes the human-computer interface, which makes the four-point robust statistics more intuitive and convenient, At the same time, the design procedure is validated, and the results show that it works well.
