Jan 24: Assignment 2 Questions
Fragment of a discussion from Course talk:STAT 550 2013
1. The researchers did chi-square and Fisher's exact test for comparisons, and I wonder whether they can fit some models for this study.
2. In page 522, Real acupuncture treatment, it points out that some possible feelings was explained to the patients in the real treatment group. However, not in the sham group. Suppose patients ever talked with each other, would they find whether they received the real or sham treatment? Would it have influence on the outcome?
