Notes
  • Multivariate multiple regression analysis is used to model the relationships between two sets of variables, the y-set of response variables and the x-set of explaining variables. In trying to have useful information about the nature of the relationships between the two sets, Ter Braak (1990) proposed a graphical display taken up again by Ramírez et al. (2005) in an independent way. In this paper, indexes of the quality approach are considered: a) those y variables better explained by x variables, b) clusters of y variables whose predictions are strongly correlated and c) subsets of x variables more correlated with a specific y variable. The graphical device considered is a generalized GH-Biplot (Gabriel, 1971) using latent variables generated by a canonical correlation analysis. The graphical display was used to analyze the Human Development Index corresponding to the 23 states of Venezuela related to several social and economic indicators.
