Table 3.

Table of r² coefficients from regressions of observed and predicted instantaneous forces for each force–moment component.

locust	X	Z	M
R	0.72 (0.42)	0.86 (0.02)	0.85 (0.76)
G	0.61 (0.47)	0.71 (0.02)	0.73 (0.69)
B	0.45 (0.25)	0.79 (0.03)	0.48 (0.41)

Values in bold correspond to the r² coefficients for regressions on forces predicted by the full linear periodic models (equation (4.10), table 2). Values in roman typeface correspond to r² coefficients for forces predicted by the equivalent linear time-invariant models, calculated using only the zeroth harmonics. There are ca 5.25×10⁶ data-points in each regression.
