Theoretical and methodological issues of using Cobb-Douglas function with constant elasticity of substitution of resources (CESfunction) in the process of modeling the most important economic indicators of production discussed. The properties of these functions, in particular, their relationship, the elasticity of substitution of resources, dependence on capital-labor productivity, the possibility of a practical estimation of their parameters in an economic studied. The existing literature approaches to the choice of the mathematical form of the function depending on the simulation output of the production factors analyzed. Probabilistic and statistical aspect of this choice and the option of a preliminary determination of suitability is Cobb-Douglas function with valid waiver of any software needed to be sure when using CESfunction also considered. The application of mathematical form of functions of the elements of the theory of statistical tests: statistical hypothesis testing, power of the tests, the necessary sample size, and others considered.
production function, statistical hypothesis testing, estimation of coefficients CES-function.
