【導讀】設施建設方面哪些因子更重要。,城市路燈(盞)。運用數(shù)據(jù)分析軟件SPSS,得到在市政設施各個指標的相。地質學,以及體育科學等各個領域都取得了顯著的成就。的繁瑣,使得因子分析法在生活領域的各個方面得到了廣泛推廣。持樣本點在高維空間中的某些結構,用降維的思想把多指標轉化為少數(shù)幾個綜合指標。幾個不可測的綜合指標通常被稱為公共因子,因子分析是根據(jù)相關性的大小將原始變量分組,使組內變量相關性較高,組間變量相關性較低。但若求出的各公共因子的典型代表變量不很突出,則應通過適當方法進行因子旋。轉,以求能較好的解釋公共因子,常用正交旋轉來解釋公共因子。具體數(shù)據(jù)見下表:。有力用因子分析后的表格說明問題。截圖二是主成分列表,表中列出了所有的主成分,且按特征根從大到小次序的排列。因子得分系數(shù)矩陣中,得出了各個變量的線性組合表達的主成分。城市排水管道長度,這三項指標所占比重最大。顧城市橋梁,城市污水日處理能力,城市路燈的建設。

  

【正文】 ty municipal facilities evaluation, using powerful application of data analysis software SPSS, the simplified calculation method, through the input data sources, that each evaluation charts, to analysis in city municipal facilities which factor is more important. This paper introduces the 31 regions city of urban facilities six index, year end has a road (km), the length of the end of actual road area (square meters), the city bridge (a), urban drainage pipe length (km), urban sewage, processing power (square meters), the city street lamp (light). Use data analysis software SPSS, get in municipal facilities all indexes, the correlation of the ponent list, table and load factors to reflect each factor matrix, the correlation of different variables, the variation can by what factors explain. Through the factor, it can be seen that the proportion of urban public utilities which index is more important. Key word: factor analysis, SPSS, data analysis, and the correlation
