This is because the demographic differences usually correspond to the autonomic changes at the overnight mean level. All Rights Reserved. In case of disagreement, the consensus annotations between the two raters were obtained. Foussier, and X.
Calculate subject CV and find the mean. The primary effects come from the physiological variability between and within subjects, markedly limiting the sleep staging performance. We considered different cohort sets including three age groups: In other words, we intended to answer the question, what sleep staging performance can be achieved if we can eliminate the effects caused by the between- or within-subjects variability?

Long, R. Seibel MJ. Six representative parameters obtained from 165 overnight heartbeat and respiration recordings were analyzed.
For example, the Q-Q plots of the residual variances in Model 1 for all the parameters are shown in Figure 3 , suggesting that the variances were approximately drawn from a normal distribution. The respiratory peaks and troughs were detected by locating the signal turning points based on sign changes of signal slopes.
