Its focus is on estimation of integral Croatian Counties models by multiple Monte Carlo simulations. The main intention is to quantify each partial influence of a set of independent regional variables (employment, gross investment, production of more important agricultural products, GVA per person employed, value of construction works, exports, imports, foreign tourist arrivals, foreign tourist nights, ecology\dots) on the regional GDP per capita. An integral part of this paper is the comparative analysis with the results given by the classical approach of econometric multiple regression. rv:
