This is a subheading in dataset information (metadata) referring to whether the statistics were collected using standard methods, statistical frameworks, and classifications. Adherence to these standards improves the ability of the information to be combined and compared with other sources.
a measure of how similar in frequency two signals are. Reflects the amount of information shared between (or common to) two site, or between two sites and a third (or more) site(s). This is computed as a correlation coefficient between the channels, and varies from 0 to 1.0, or from 0 to 100%. Coherence training is important, as it allows neurofeedback to be used to train the amount of coupling or connection between brain locations, as the brain functions.
In probability theory and statistics, coherence, like correlation, gives a measure of the dependence of two random variables.
