PEREZ, RAÚL ALBERTO; LERA, LYDIA  e  BOQUET, ANA. Double Principal Components Analysis for Categorical Data and its Application to a Migration Study. Rev.Colomb.Estad. [online]. 2006, vol.29, n.1, pp.17-34. ISSN 0120-1751.

We adapted the double principal component analysis (DACP) (Bouroche 1975), developed for the analysis of three-dimensional quantitative data, to categorical data by mean of the Chi-squared distance between rows and columns profile of a contingency table and we carry out an application to a study of internal migration in Cuba.

Palavras-chave : Double principal component analysis; Categorical data; Common structure.
