The coefficients of variation for repeatability and reproducibility in assessments of anti-Xa activity were 1.0%and1.2%2%, respectively.
For vertical linear driving mechanism, the variation of resolution and repeatability induced by its axial deformation and radial deformation is analyzed.
The random variation expressed as coefficients of repeatability for several time intervals are presented.
In addition, we show how random effects analysis of variance, which forms the basis for ICC, can be used to derive additional test-retest metrics, which are generally not reported in the PET brain imaging test-retest literature, such as within-subject coefficient of variation and repeatability coefficient.
The analyses focused on making inferences on the individual variation and repeatability of CH4 production (l/day, l/kg EDMI and l/kg ECM).
To analyze patterns of variation in repeatability estimates, we used t tests, in which t values were calculated based on weighted means and weighted variances (where the weights are the years-specific sample sizes, i.e., the number of individuals, see Table 3).
The mean variation coefficients, as a measure of repeatability, are also presented (Table 3).
Analysis of camphor variation supports the repeatability of the method, accounting for 18.3% as relative standard deviation throughout the whole dataset.
Improvements of interventions taking more than one day can be considered as beyond random variation when the inter-day coefficients of repeatability are taken into account.
