a
Relevant formulae are shown in parentheses (see text)
b
Accuracy = % of correct phasic and non-phasic GMM predictions compared to consensus visual scoring
c
TP = true positives (% of seconds with phasic activity assessed visually that were correctly classified by the GMM for that feature)
d
TN = true negatives (% of seconds without phasic activity assessed visually that were correctly classified by the GMM for that feature).
