为了寻求一种有效的房地产预警指标选择方法，基于定量方法并与定性方法相结合，在现有房地产指标数据库的基础上，通过聚类分析和非参数检验，建立了一套预警指标体系，然后利用它对上海市房地产市场进行了扩散指数（DI）预警实证分析。结果表明，基于聚类分析和非参数检验的预警指标体系可以较为准确地对房地产市场的景气状况进行客观度量，这种指标选择方法是有效的。

Real Estate Early Warning Index Selection by Cluster Analysis and Nonparametric Test

The construction of the early warning index system is the prerequisite of the real estate market early warning system. There are two methods to set up the early warning index system, the quantitative method and qualitative analysis. Combined with qualitative method, this paper used the cluster analysis and nonparametric test to set up the early warning index system. Then utilized this system to carry analysis on Shanghai real estate market diffusion index (DI). To a certain extent, the DI can calculate and forecast the tendency of Shanghai real estate market, so this method of early warning index system selection is useful.
