Table 5.

Results with σ_ApAq fixed to its true value (row A), and σ_ApAq fixed to equal zero (row B)

	σ²_Ap	σ²_Aq	σ_ApAq	σ²_A	σ²_C	σ²_E	σ_AC	LLR	Power
A	0.20	0.30	0.1224*	0.745^a	0.2	0.3	0.077	6.81	0.742
B	0.5199	0.2250	0*	0.745^b	0.2	0.3	0.077	6.81	0.742

σ_ApAq = 0.122 corresponds to a correlation of 0.1224/sqrt(0.20*0.30) = 0.5

σ_AC = 0.077 corresponds to a correlation of 0.077/sqrt(0.745*0.2) = 0.2

Power: to reject σ_AC = 0 is given α = 0.05, and Nmz = 1000, Ndz = 1000, based on the LLR statistic
