TABLE I.

Mean (± std.) eigenvalues for the LDS model parameters. Eigenvalues for each 2 × 2 matrix parameter were sorted in descending order and then averaged across subjects. For Q and R, the square-root of the eigenvalues was used, and so the parameters represent standard deviations and have units of mm. A and B are dimensionless.

	Mυ	Mp
A	[0.97 0.89] ± [0.03 0.09]	[0.77 0.52] ± [0.13 0.23]
B	[-0.36 -0.18] ± [0.18 0.10]	[-0.38 -0.18] ± [0.18 0.10]
$Q^{\frac{1}{2}}$	[8.7 4.2] ± [4.4 2.4]	[6.2 2.5] ± [3.4 1.18]
$R^{\frac{1}{2}}$	[12.3 9.1] ± [5.1 3.2]	[14.6 11.0] ± [5.5 4.1]
