Since the first eigenvalue represents the major motion component and the second eigenvalue represents the minor motion component or turbulence, they are more useful to detect true motions while more successfully suppressing false alarms.
We can compare the first eigenvalue of q with the first eigenvalue of its rearrangement.
Matrices were normalized for size variations by dividing each individual matrix by its first eigenvalue.
No significant clusters were found in which cocaine-dependent subjects had significantly different first eigenvalue (λ1) compared to control subjects.
The first eigenvalue should be significantly higher than the second eigenvalue.
The first eigenvalue was 5.16 and the second was 1.17.
A large first eigenvalue (16.6) and much smaller subsequent eigenvalues (3.5 and lower) suggested a leading global factor.
The first eigenvalue was 6.8 dropping to 1.1 for the second and 1.0 for the third.
Axial ADC and radial ADC were obtained, which were the first eigenvalue of the diffusion tensor, and the average of the second and third eigenvalues of the tensor.
The EFA scree plot strongly suggested a single factor, as did the ratio of the first eigenvalue to the second eigenvalue (9.31 0.44).
