Abstract:
|
We develop minimum size sample plans that approximately achieve specified Type-1 and Type-2 error rates when testing multiple treatment groups versus a control group. The plans assume the Weibull distribution family adequately describes the underlying survivor functions, and we separately consider three of the most common study scenarios: a) complete samples, b) Type-1 censoring with a common censoring time, and c) Type-1 censoring with an accrual period. A large-scale mice longevity study comparing the effect on survival of multiple low-calorie diets is used to motivate our work on this problem.
