Results should provide a better understanding of the relationship between functional form and estimated income and household size elasticities. In addition, since one criterion for selecting functional forms is goodness of fit, the study should indicate which forms are most appropriate for estimating Engel relationships.The interpretation of this measure of goodness of fit varies, depending on whether the dependent variable is transformed before estimation. For example, for the double logarithmic functional form, the computed corre lation coefficient measures the corre lation between the natural logarithm of observed expenditure (quantity) and the predicted value for the natural logarithm of expenditure (quantity).However, for the linear functional form, the correlation coefficient measures the correlation between observed expenditure (quantity) and predicted expenditure (quantity). Thus, a more consistent measure of goodness of fit would be to trans form the predicted values for the double logarithmic functional form to natural numbers before comput ing the correlation coefficient.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
