Abstract
Longitudinal panel designs: alternative data analysis with structural equations.- The use of the longitudinal panel design for the study of the temporal effect on the variables relationships, seems a valid alternative for of obtain empirical evidence about the hipothetical causal relation between variables. However, the traditional analysis of the differents correlations present some deficiencias, essentially centrated in the difficulty for to show the true effects between variables. The aim of this paper is to present the translation of the differents statisticals models referred with the panel design with two waves (2w2v); lo the structurals equations system and, also, the improvements of this kind of analysis, with respect of the study of the differents effects of this procedure research.
