Tools for econometric analysis and economic modelling with the traditional twoinput Constant Elasticity of Substitution (CES) function and with nested CES functions with three and four inputs. The econometric estimation can be done by the Kmenta approximation, or nonlinear leastsquares using various gradientbased or global optimisation algorithms. Some of these algorithms can constrain the parameters to certain ranges, e.g. economically meaningful values. Furthermore, the nonlinear leastsquares estimation can be combined with a gridsearch for the rhoparameter(s).
