The standard deviation of F0 was measured and latency was defined as the time between solution change and the point at which F/F0 first deviated above F0 by more than four standard deviations.
The point at which this plot deviates from linearity can be used as a threshold separating true positives from random scores [ 48].
With an approach that is more realistic at the bedside, the Pcp can be measured using a graphical method; the Pcp is estimated as the point at which the pressure curve deviates from the slope of the first rapid decay.
Kim et al [ 18] have suggested a solution to array-specific variance and normalization bias by determining thresholds specific to each array based on the point at which the LR distribution deviates from its inferred normal distribution.
Temporal resolutions of up to 50 Hz are available using these techniques (Elsabbagh et al., 2009); spatial resolution is low, but this is nonessential for tasks such as the present task, in which the aim is only to estimate the point at which the eyeball first deviates from the midline following a successful fixation.
The threshold of P < 1 × 10−3 corresponded to the point at which endometriosis GWAS results started to deviate from the null distribution (evidence for association) in the overall and Stage B endometriosis Q Q plots (Supplementary Material, Fig. S4).
The point at which bias in the reconstructed images deviates from 10% of the average activity concentration at lower activities (i.e. not affected by dead time) can also be noted at 78.5 Mcps.
Action potential threshold was defined as the point at which the derivative of the membrane potential dV/dt deviated from the mean baseline value by >2 standard deviations [46], and was calculated using routines developed in our laboratory (Figure S2).
The clinician also objectively assessed the point at which the subject lost fixation, when one eye deviated.
The clinician also objectively observed the point at which the subject lost fixation, when one eye deviated.
Thus, ITDs become ambiguous as they deviate from the midline, but the precise point at which ambiguity occurs depends on the sound frequency.
