In this paper, we propose a new method called dual STATICO (DSTATICO), which is an extension of STATICO in the case where two multi-tables (horizontal) superimposed individuals are structured according to a partition of the variables. The goal is to study starting from the combination of the dual co-inertia analysis and the partial triadic analysis of the proximity variability between pairs of tables having the same variables. An example of this method consisting being studied of the compared economic evolution of the countries of the Economic and Monetary Community of Central Africa (EMCCA) and the West African Economic and Monetary Union (WAEMU) is given. This method was programmed with the software scilab and the charts with the software R.
