徐州市住宅价格预测及合理性评价
文章结合各地区住宅价格预测的实例，论述了徐州市商品住宅价格预测的基本原理、方法，并通过建立标准差模型对徐州市商品住宅价格的合理性进行了评价。本文从影响商品住宅价格的因素着手研究，选择主要因子构建徐州市商品住宅价格预测的多元回归模型,对徐州市2014年的商品住宅价格进行了预测和检验。
文章根据徐州市2007年-2014年的徐州市统计年鉴数据，利用SPSS软件，采用逐步回归分析的方法，对该地区的住宅价格进行了模拟预测。在采用趋势分析法下，得出的公式为：
代入已有数据，用该方程预测出的2014年的徐州市商品住宅平均价格为8788元。
在逐步回归分析下的预测结果如下，线性回归方程为：
代入已有数据，可以得出方程的结果7921.72元就是2014年徐州市商品住宅平均价格。取两模型结果的平均数8354.86元作为2014年徐州市商品住宅平均价格的最终预测值。
最后通过建立标准差模型对徐州市商品住宅价格的合理性进行了分析和评价，发现Z1即2007年到2013年徐州市房价收入比均不在合理区间内； 只有2010年和2011年徐州市的房价成本比处于合理区间内。所以，综合来看2007年到2013年徐州市住宅房价均不合理。

Articles based in Xuzhou City in 2007 --2014 year Xuzhou Statistical Yearbook data, using SPSS software, using stepwise regression analysis, the region's housing prices were simulated to predict. In the case of trend analysis, the resulting formula is：
Into the existing data, using the equation predicted 2014 Xuzhou commercial housing price 8788 yuan.
