Likelihood estimations for the two nested models

Model	Free Parameters	Best estimate Nes	Support limits	Maximum likelihood
Model 1	s	−1.47	−1.97 to −0.94	−395.81
Model 2	s TR	−0.29	−1.17 to 0.91	−392.31*
	s FL	−1.98	−2.8 to −1.1

*Significant improvement from model 1, P < 0.01, likelihood ratio test.
