This research work compared the power of some specification error test using bootstrapping experiment to generate the data for each of the models at different sample sizes (n) 20, 30, 50, and 80 respectively, each with 100 replications(r). The models in this research consist of three omitted variables. For the models considered, the experiment reveals that the Ramsey Regression Equation Specification Error Test (RESET test) is more efficient than that of Q test in detecting the error of omitted variable in specification error.
