STA 101: Properly setting up and designing a clinical
... “Sample size calculation were based on a prestudy survey of 26 surgeons, which indicated that the baseline 5-year survival rate of D1 surgery was expected to be 20%, and an improvement in survival to 34% (14% chance) with D2 resection would be a realistic expectation. Thus 400 patients (200 in each ...

... 5. For p ∈ (0, 1), let z p denote the quantile of order p for G and y p the quantile of order p for F. Show that y p = a + b z p From Exercise 5, it follows that if the probability plot constructed with distribution function F is nearly linear (and in particular, if it is close to the diagonal line) ...
