Procedura „stopniowego” konstruowania liniowych modeli ekonometrycznych o wielu zmiennych objaśniających

Abstract

The “step by step” procedure of constructing linear econometric models with many endogenous variables presented in the article consists in arranging them according to their importance measured with the strength of the relationship with the exogenous variable and the follow-on connection 1. of the first in the established succession endogenous variable with the exogenous variable and calculating the model residuals, so that 2. they would be model-connected with the next variable and once again calculate the residuals of the model received. One deals with them as with the residuals in point 2 and one goes on with the procedure until the set or endogenous variables is exhausted. The final model is received by addind all partial models. This procedure is explained in terms of an empirical example.
