POWER OF THE TESTS DENGAN NON-SAMPLE PRIOR INFORMATION PADA PENGUJIAN HIPOTESIS SATU ARAH

Abstrak

The research discussed power of the tests with  non-sample prior information (NSPI) in testing intercept on one-side-hypothesis. The testing is condcuted on a simple regression model (SRM) and multivariate simple regression model (MSRM), and the power of the tests are unrestricted test (UT), restricted test (RT), and preliminary-test test (PTT). The method for choosing the best  tests is a maximum power and minimum size. A simulation study and graphical analysis are given using generate and real data. The result showed that the power of the test of the PTT  are an alternative choice  among the tests on both SRM and MSRM.
