Type-I error and power (α=0.05) of the four methods for data simulated from NBMM and CPMM

	Data from NB-sim						Data from CP-sim
Method/ ${\sigma }_g^2$	0	0.10	0.25	0.50	0.75	1	0	0.10	0.25	0.50	0.75	1
CP-fit	0.10	0.78	0.89	0.94	0.96	0.97	0.04	0.72	0.86	0.92	0.96	0.96
NB-fit	0.04	0.71	0.86	0.92	0.95	0.95	0.04	0.72	0.86	0.92	0.96	0.96
VST	0	0.56	0.76	0.86	0.90	0.92	0	0.55	0.76	0.86	0.90	0.92

The value in a cell denotes the value of the power function (rounded off to 2 places after decimal) for each case. The value of ${\sigma }_g^2$ drives the power. The case ${\sigma }_g^2=0$ reflects the null hypothesis, therefore corresponding the cell value is the type-I error. Columns with ${\sigma }_g^2>0$ indicates the power for increasing strain specific variance
