Abstract

The invention provides a method and a system for predicating an economic index based on regression analysis. According to the method and the system for predicating and analyzing city economy, dimension reduction processing of original data is realized through a main component analysis method; advantages in predicating methods such as neural network, support vector machine and gray system theory are combined; and through regression analysis, a more reasonable predication process is obtained; analysis for predication of the city economic index facilitates mastering for operation condition of thecity economy; and the method and the system support analysis and early-warning for future development of the city economy.

Description

technical field [0001] The invention relates to a method and system for predicting economic indicators based on regression analysis, belonging to the technical field of artificial intelligence, especially artificial intelligence related to smart cities. Background technique [0002] With the popularization of Smart City 2.0, the use of artificial intelligence has attracted more and more attention. In the field of urban operation, urban managers are increasingly relying on artificial intelligence to make economic forecasts, analyze economic development processes and phenomena, and judge the rationality and scientificity of economic development guidelines and policies. [0003] The economic forecasting methods in the prior art are often based on a single model, using a specific algorithm to obtain forecasting results. However, urban economic changes are non-linear, and there is information redundancy in various influencing factors. It is difficult to guarantee the accuracy an...
