„Wzajemne" funkcje regresji i równoczesne zależności między zjawiskami ekonomicznymi

Abstract

The non-reversibility of the regression functions, the simultaneous relations between the economic phenomena and the so-called paired regression functions are treated on the basis of cybernetic considerations. It is shown, that the treatment of this type of regression functions requires the existence of simultaneous relations and multicollinearity, which leads, in turn, to based results, when estimating them seperately on the basis of the classical Least-Squares-Method.
