Although both the MMN and P300 are indices of change detection, they are structurally dissociable: the neural assemblies that generate these waveforms are situated in different regions of the brain.
Two of these responses, the MMN and P300, are established indices of change detection and, since TD subjects are unaware of melodic distortions, we predicted that both of these responses would be absent in these individuals in response to distorted notes.
The distribution-based methods reflect one or several statistical indices of change.
Malmquist-DEA is applied to panel data to calculate indices of changes in Total Factor Productivity (TFP), technology, technical efficiency, and scale efficiency.
Myocardial strain and strain rate are dimensionless indices of changes in length that reflect tissue deformation [ 65].
The dose-independent induction of the serum creatinine may be attributable, as already reported (Amin et al. 2004), to the fact that this parameter, like serum urea, traditionally used as indices of changes in glomerular filtration rate, is a relatively insensitive marker of glomerular injury.
FASHION, they say, is an index of change, registering shifts in confidence and mood too subtle to glean from the rise and the fall of the Dow.

In this event, it would be important to measure success using an index of change across behaviors, such as that proposed by Prochaska and colleagues [ 6].
The applied goal of this instrument is to improve early detection of bulbar involvement and to provide a reproducible, quantitative index of change in the rate of bulbar progression.
This, in combination with the results from responsiveness to change analysis, suggests that the PGI cannot be relied upon as an index of change in quality of life in this patient population.
