2. In the following example, the researcher was interested in determining if the following index (x) was associated with (v), remission in cancer patients. The index x measures proliferation activity of cells after a patient receives an injection of tritiated thymidine. The response variable y indicates whether the patient achieved remission (1), or did not achieve remission (0).
