Table 3.

Range of the power difference (in %) between the 1:3 matching and the 1:1 matching for four testing models (Multiplicative, Dominant, Recessive, 2df) and four true genetic models (Multiplicative, Dominant, Recessive, and Additive) in the single-locus analysis. A negative value means the 1:1 matching is more powerful, while a positive value means the 1:3 matching is more powerful.

Testing model	Multiplicative	Dominant	Recessive	2df
True model	Multiplicative	Dominant	Recessive	2df
Multiplicative	[0, 0.4]	[−4.5, 0]	[−5.1, 0.1]	[0, 0.5]
Dominant	[−2.2, 0]	[0, 2.1]	[−7.6, 0]	[0, 2.2]
Recessive	[0, 6.6]	[−51.9, 0]	[0, 15.0]	[0, 16.3]
Additive	[−0.4, 0]	[−2.2, 0]	[−11.2, 0]	[0, 0]
