Neurofeedback (also called neurobiofeedback or EEG biofeedback) usually refers to frequency-based biofeedback that uses an EEG to give clients information about their brainwaves and gradually and subtly teaches people how to alter their brainwave activity.
Considering up to 5% deviations from the expected frequency of occurrence as normal stochastic variations, 'random' refers to frequencies in the normal range, i.e., (25 ± 5%), while 'high' and 'low' refer to frequencies >30% and <20% respectively.
'Opposite sign', 'Same sign', and 'GMR type' refer to frequency vs capacitance curves when β = −10%, β = 10%, and β =0%, respectively.
These questions referred to frequency of physical activities separately for the summer and winter months, in three different settings (i.e., home, work, and leisure), with ratings from 1 (never) to 6 (several times a week).
Hence, the two items referring to breaks in sitting time, and the item referring to frequency of snack food consumption, demonstrated moderate agreement.
If the classification is to be performed in the wavelet domain, wavelet coefficients which refer to frequency bands lying below 150 Hz should be avoided.
It could be they weren't monitoring the guard frequencies," he said referring to frequencies that all air towers are supposed to monitor.
Hence, for Bayesians probabilities refer to a state of knowledge, whereas for frequentists probabilities refer to frequencies of events (see, e.g., Sober 2008, chapter 1 for a detailed introduction to Bayesianism and frequentism as well as to likelihoodism).
