A Criterion of Testing the Goodness of Fit of a Model

The literature indicates that R-square as a test of goodness of fit of a model is sometimes misleading. A low R-square value does not mean a poor fit. Another criterion, the AIC (Akaike Information Criterion) is gaining popularity in academic circles. Computer simulation of different functional forms will be run and a comparison will be made between R-square and AIC.
