Testing the equality of the two intercepts of two parallel regression models is considered when the slopes are suspected to be equal. For three different scenarios on the values of the slope parameters, namely (i) unknown (unspecified), (ii) known (specified), and (iii) suspected, we derive the unrestricted (UT), restricted (RT) and pretest (PTT) tests for testing the intercept parameters. The test statistics, their sampling distributions, and power functions of the tests are obtained. Comparison of power functions and sizes of the tests are provided.
