10.6. Research Question 1, Continued: Crucial Error Rates for Mortality Analysis
In developing the statistical considerations for the QCA/malaria trial, Dr. Gooden understands the value in assessing its crucial Type I and Type II error rates, and she presses her CHI colleagues to complete the exercise faithfully. As mentioned before, they are optimistic that QCA is effective, but to compute crucial error rates, they must now quantify that optimism by setting γ. Initial discussions place γ near 0.75, but the 0.30 value reported by Lee and Zelen (2000) tempers their thinking substantially. They settle on γ = 0.50. Dr. Gooden will also use γ = 0.30.
