A study on the specification of the disturbance term in estimating the indirect addilong engel curve system

This paper deals with the procedure selecting the error specification in estimating empirically the indirect addilog Engel curve system. When the disturbance term is specified additively, three different estimated models are derived for the above system under consideration. In case of muliplicative specification two different estimated models are generated. And the best one is selected in the goodness of fit for the given sample data as a whole by comparing five different estimated models’ performance in terms of Theil’s average imformation inaccuracy mcasurc.
