摘要:

Permutation tests based on certain ratio statistics have been used (a) in the analysis of rainfall stimulation experiments and (b) in simulation studies aimed at providing guidance in the planning of such experiments. The paper presents asymptotic approximations to the permutation distributions of these statistics, and also to their power functions under a simple multiplicative model for the seeding effect. Simulation results are presented for comparison with the theoretical approximations.
