摘要
logit函数是描述一个问题发生与否的概率函数,6σ是统计学原理在质量管理等方面应用而产生的监测和检测方法,通过这两个方法监测石油价格变化对经济的影响程度。利用数学推导及证明,得到了用于监测的核心指标——石油支出占GDP的比重,并通过对这一指标进行实证分析,得到与实际情况比较相符的结论。
Logit is a probability function that describe whether a problem arise or not,and 6σ is a monitoring and inspection method of statistical principle applied in quality management. In the paper, the two methods were combined to monitor the impact of oil price change on economy. Using mathematical derivation, it is proved that oil expenditure proportion of GDP is the core monitor indicator. And the demonstration analysis of this indicator with above mentioned methods show that the result is consisfent with the actual situation.
