Actiware scores all epochs as either sleep or wake. Whether a particular epoch
is scored as wake is determined by comparing activity counts for the epoch in
question and those immediately surrounding it, to a threshold value set by the
researcher. If the number of counts exceeds the threshold, the epoch is scored as
wake. If it falls below, or is equal to, the threshold, the epoch is scored as sleep.
Sleep = TotalActivityCounts≤Wake Threshold Value
Wake = Total Activity Counts > Wake Threshold Value
Calculating Total Activity Counts
Actiware calculates total activity counts based on the sampling epoch. Below are
four diagrams showing how this scoring calculation is done.
