KUBRUSLY, Lucia Silva. UM PROCEDIMENTO PARA CALCULAR ÍNDICES A PARTIR DE UMA BASE DE DADOS MULTIVARIADOS. Pesqui. Oper. [online]. 2001, vol.21, n.1, pp. 107-117. ISSN 1678-5142. http://dx.doi.org/10.1590/S0101-74382001000100007.
This paper presents a solution to the problem of finding an index number I for ranking a set of n objects, according to criteria defined by a set of m variables. In general, it is necessary to choose a suitable set of variables, and weights for each variable. Cluster Analysis is used for variable selection, and Principal Component Analysis is used to attain weights. Two applications are presented.
