RETRACTED ARTICLE: Design of early warning multimedia computer system for real estate market under PROBIT model

Abstract

The economic benefits brought by real estate are undoubtedly huge for the country and society, but once the real estate market has a serious credit crisis, the whole macroeconomic turmoil will even lead to economic collapse. Many scholars have conducted relevant research on the risk warning of the real estate market, but most of the research is too limited and the early warning system lacks reliable basis and accuracy. Therefore, based on the importance of the real estate economy, it is very important and meaningful to study a system that can accurately and reliably predict the real estate market. This paper abandons the disadvantages of traditional models such as unreliability and innovation based on the Probit model principle. Based on the data of the Nanjing regional real estate market from 2008 to 2018, the macroeconomic variables of this decade and their related real estate economic variables are horizontally and vertically. The real estate market early warning system was constructed and its risk verification analysis was carried out. Finally, based on this system, the real estate market risk of Wuxi City in the first two quarters of 2016 was verified. The verification results show that the early warning rate based on the early warning system proposed in this paper is 85%.
