统计量化测度和统计模型是统计学的核心,从统计学诞生之日起,其生命力就在于能够对现实进行量化测度和用统计模型分析实际问题。没有量化测度,经济统计学就不会相对独立于经济学。没有模型应用,数理统计学就还是数学,就不会从数学中分离出来。目前社会已经发展到网络和大数据时代,传统和现代的统计模型无论在方法上还是在应用中都已经受到了挑战。 Statistical quantification and statistical models are the core of statistics. From the date of birth of statistics, their vitality lies in the ability to quantify the reality and analyze the practical problems with statistical models. Without quantitative measures, economic statistics will not be relatively independent of economics. Without a model application, mathematical statistics are still maths and can not be separated from mathematics. At present, the society has been developed to the era of network and big data. The traditional and modern statistical models have been challenged both in terms of methods and applications.
