All the points fall between the upper and lower LOA for both end-expiration and end-inspiration; and all the points are distributed equally above and below the mean line which indicates little to no bias (Fig.
At 1 month, the mean line improvement increased more rapidly in group I and group III than in group II.
This descriptor is explained in equation 2, where D[V.sub.Dn] is the disc wear volume below the surface mean line, B[V.sub.Dn] is the ball wear volume and D[V.sub.Up] is the disc wear volume above the surface mean line.
Statistical analysis was performed to determine the interaction of signal fluctuation type (periodic, chaotic, or random), manipulation (frequency, amplitude, or both), and frequency ratio (1:1, 2:3, 1:2, 2:5, 1:3, 2:7, and 1: 4) for each of the dependent variables (xSE, % DET, max line, mean line, and cRQA entropy).
The mean line sensitivity is [approximately equal to]0.44%/V, for supply voltages ranging from 0.45 to 1.8 V.
Biases are clearly visualized with the B-A plots--a constant bias is evident as a central, mean line that is not at 0, and a proportional bias shows as a sloped, central line.
As previously mentioned, the sensitivity of the linear filter to outliers may result in the mean line deviating severely from the actual distribution.
Next, the annual mean for the yield record was plotted, and the difference between the mean line and the Upper Bound defined the equivalent range of corn yield for the Lower Bound.
And The Tiki Bar just across the road does a mean line in cocktails, for those really wanting to push the boat out.
[R.sub.a] is the average distance from the profile to the mean line over the length of assessment.
