An index of need for health resources in the Indian States has been developed using the statistical technique of factor analysis. Data on seven selected indicators measuring various aspects of population health in 17 Indian States for the year 1981 were used to extract factors. Two factors were discovered which together explained 83% of the total variation. The first factor alone, identified as 'proximate determinants', explained 67% of the variation. The second, 'sociomedical background' accounted for 16%. Factor analysis results have been used to derive standardized indices which helped to compare quantitatively the health needs of the people of various States.
利用因子分析这一统计技术，编制了印度各邦卫生资源需求指数。1981年从印度17个邦选取了七个衡量人口健康各个方面的指标数据来提取因子。发现了两个因子，它们共同解释了总变异的83%。单独的第一个因子，被确定为“近因决定因素”，解释了67%的变异。第二个因子“社会医学背景”占16%。因子分析结果已被用于得出标准化指数，这些指数有助于定量比较各邦人民的健康需求。
