SIMUL 3.2: An Econometric Tool for Multidimensional Modelling
Initially developed in the context of <InlineEquation ID="IEq1"> <EquationSource Format="TEX">$${\tt REGILINK}$$</EquationSource> </InlineEquation> project, <InlineEquation ID="IEq2"> <EquationSource Format="TEX">$${\tt SIMUL 3.2}$$</EquationSource> </InlineEquation> econometric software is able to estimate and to run large-scale dynamic multi-regional, multi-sectoral models. The package includes a data bank management module, <InlineEquation ID="IEq3"> <EquationSource Format="TEX">$${\tt GEBANK}$$</EquationSource> </InlineEquation> which performs the usual data import/export functions, and transformations (especially the RAS and the aggregation one), a graphic module, <InlineEquation ID="IEq4"> <EquationSource Format="TEX">$${\tt GRAPHE}$$</EquationSource> </InlineEquation> , a cartographic module, <InlineEquation ID="IEq5"> <EquationSource Format="TEX">$${\tt GEOGRA}$$</EquationSource> </InlineEquation> for a “typical use”. For an “atypical use” the package includes <InlineEquation ID="IEq6"> <EquationSource Format="TEX">$${\tt CHRONO}$$</EquationSource> </InlineEquation> to help for the WDC (Working Days Correction) estimation and <InlineEquation ID="IEq7"> <EquationSource Format="TEX">$${\tt GNOMBR}$$</EquationSource> </InlineEquation> to replace the floating point arithmetic by a multi-precision one in a program. Although the current package includes a basic estimation’s (OLS) and solving’s (Gauss–Seidel) algorithms, it allows user to implement the equations in their reduced form <InlineEquation ID="IEq8"> <EquationSource Format="TEX">$${Y_{r,b}=X_{r,b} + \varepsilon}$$</EquationSource> </InlineEquation> and to use alternative econometric equations. <InlineEquation ID="IEq9"> <EquationSource Format="TEX">$${\tt SIMUL}$$</EquationSource> </InlineEquation> provides results and reports documentation in ASCII and <InlineEquation ID="IEq16"> <EquationSource Format="TEX">$${\hbox{\LaTeX}}$$</EquationSource> </InlineEquation> formats. The next releases of <InlineEquation ID="IEq10"> <EquationSource Format="TEX">$${\tt SIMUL}$$</EquationSource> </InlineEquation> should improve the OLS procedure according to the Wilkinson’s criteria, include Hildreth–Lu’s algorithm and comparative statics option. Later, the package should allow other models implementations (Input–Output, VAR etc.). Even if it’s probably outclassed by the major softwares in terms of design and statistic tests sets, <InlineEquation ID="IEq11"> <EquationSource Format="TEX">$${\tt SIMUL}$$</EquationSource> </InlineEquation> provides freely basic evolutive tools to estimate and run easily and safety some large scale multi-sectoral, multi-regional, econometric models.
