Power of MDR (from Ritchie et al. 2007) to detect primary genetic model in data with genetic heterogeneity.

Source of Noise	Power (%) to Detect Primary Model (5,10)
	Model 1	Model 2	Model 3	Model 4	Model 5	Model 6
GH	30	18	19	25	8	8
GE+GH	39	18	19	25	8	8
GH+PC	11	18	5	3	4	2
GH+MS	28	23	19	19	9	13
GE+GH+PC	10	18	8	4	3	3
GE+GH+MS	29	22	21	20	7	4
GH+PC+MS	12	22	5	5	2	4
GE+GH+PC+MS	16	17	4	3	1	3

GE = 5% Genotyping Error; GH = 50% Genetic Heterogeneity; PC = 50% Phenocopy; MS = 5% Missing Data
