Type I Error Rates (×10⁴) of Association Tests at the Nominal Significance Level of 10⁻⁴ When Different Proportions of the Controls with Potential Genotyping Errors Are Excluded

No. of Controls	Proportion Excluded	MAF = 0.05	MAF = 0.1
96	0	0.81	0.90
	1/2	1.26	1.13
	1	2.84	1.89
192	0	0.81	0.92
	1/2	2.39	1.77

384	0	0.74	0.81
	1/2	7.99	4.34
	1	145.0	44.1

MAF denotes minor allele frequency.
