%0 Journal Article %T THE STUDY OF CELLS IN THE ANALYSIS OF CONTINGENCY TABLES FROM THE VIEWPOINT OF RUDAS, CLOGG AND LINDSAY MIXTURE INDEX OF FIT. %A Adalberto Gonz¨¢lez Deb¨¦n y Jes¨²s E. S¨¢nchez Garc¨ªa %J Revista Investigaci¨®n Operacional %D 2009 %I Universidad de La Habana %X In this paper the state of the art of the mixture index of fit, proposed by Rudas, Clogg &Lindsay in 1994 is presented. The analysis of the unstructured latent class considered as a residual analysis of a new kind is discussed. It is concluded that it is most adequate whenever the lack of fit is due to the existence of ¡°spare¡± individuals, but it is not the same if there are ¡°lacking¡± individuals in several cells. At last, the influence of a cell on the lack of fit of a model is defined, which can be used as a complementary descriptive measure in the usual residual analysis and in the configural frequency analysis. %K Latent Class Analysis %K Rudas-Clogg-Lindsay Mixture Index of Fit %K Residual Analysis %U http://rev-inv-ope.univ-paris1.fr/files/30309/30309-06.pdf
