Spss电脑实验-第五节(7)乘法合成综合指数法

Ⅶ.乘法合成综合指数法
1. 乘法合成综合指数法所用程序文件
*Hospital evaluation by 9 methods; Filename: 9MethodsHos-7.sps.
*--------------------------------------------------------------------------.
*Method-7: Geomatric Comprehensive Index Method (2):.
*Kang Xue-Gui: CHN Handbook of Health Mornitering Statistics Report (M),
Beijing: CHN Science Techn. Publishing House, 1996, 193:.

GET FILE='c:spsssav9methodsHos.sav'.
*The variables are made into the same trend (high good); So,
the following "i=100-i" is high good:.
COMPUTE i=100-i.

*The "W" (of each index): 9 index, 1/9=0.1111:.
*When high-better, Xi/Standard; When low-better, Standard/Xi;
The standard =MEAN:.
DESCRIPTIVES VARIABLES=a b c d e f g h i /STATISTICS=MEAN.

COMPUTE ia=a/75.8400.
COMPUTE ib=b/99.0000.
COMPUTE ic=c/80.7780.
COMPUTE id=d/75.0080.
COMPUTE ie=e/88.9640.
COMPUTE if=f/98.6000.
COMPUTE ig=g/89.6680.
COMPUTE ih=h/92.2980.
COMPUTE ii=i/92.4960.

COMPUTE iaa=ia**0.1111.
COMPUTE ibb=ib**0.1111.
COMPUTE icc=ic**0.1111.
COMPUTE idd=id**0.1111.
COMPUTE iee=ie**0.1111.
COMPUTE iff=if**0.1111.
COMPUTE igg=ig**0.1111.
COMPUTE ihh=ih**0.1111.
COMPUTE iii=ii**0.1111.

COMPUTE y=iaa*ibb*icc*idd*iee*iff*igg*ihh*iii.

*The highest "Y" is the best point:.
RANK /VARIABLES=y(D) /RANK INTO No.
FORMATS No (F3.0).
SORT CASESE BY No(A).
FORMATS y(F6.3).
LIST VARIABLES=hos y No /FORMAT=NUMBERED /CASES=FROM 1 TO 5.

2. 乘法合成综合指数法的计算方法、步骤
Wj 为各指标的权数;Xij’ 为经过相对化处理后的实际值;Y 为用于评价该评价单元的综合指数。与加权线性综合指数法类似,计算综合指数Y 的公式为:
Y = ∏(Xij’Wj )= ∏(Xij’) ** Wj
3. 乘法合成综合指数法的评价结果
运行程序文件后,可计算出各医院的综合指数 Y,综合指数越大说明该医院的感染管理质量越好,5 家医院从好到差依次为 T—R—S—Q—P,见表 5-2。

HOS Y NO
----------------------------------------------
1 T 1.052 1
2 R 1.045 2
3 S 1.017 3
4 Q 0.958 4
5 P 0.922 5
