一种基于微观实物量数据的价值量推算方法
Learning method for magnitude of value based on micro-physical quantity data
摘要
Abstract
The relationship between physical magnitude and value magnitude is the core in System of National Account (SNA). Value magnitude estimation is an important problem in the research of government data quality. This paper proposes a learning method for magnitude of value based on micro-physical quantity data. It mainly concerns about enterprise micro level data, which achieves value magnitude learning based on micro-physical quantity combining variable selection algorithm, structure selection model and Structure Equation Model(SEM). With real survey on lodging industry, it evaluates the effect of SEM with different variable selection and different hybrid tree structure selection. The results demonstrate that the pro-posed learning system can compact structure and avoid design risk, and can better refine the main statistical dependencies of value magnitude for the physical quantity.关键词
