The coefficient of determination  has an important role in empirical accounting and finance when the purpose is to compare the explanatory power of the same model in different samples or between models in the same sample. For this reason, it became a standard statistical procedure to test if the differences in sampling ’s are statistically significant. Therefore, and in order to check if the difference in the  from two linear regression models with the same dependent variable is statistically significant, we propose EViews programs to compute the value of two tests for independent and nonindependent samples. These tests are commonly used in empirical accounting and finance and they cannot be computed in a standard way by the Econometric Views software.
