The phrase "absolute variance" is correct and usable in written English.
It can be used in statistical contexts to refer to the total variability of a dataset without regard to direction.
Example: "To understand the data better, we calculated the absolute variance to assess the overall spread of the values."
Alternatives: "total variance" or "overall variance".
The speed slightly increases in relative terms, although its absolute variance is not significant (<1 km/h).
The second one is the so-termed absolute variance deviation-based selection that has been advocated in the context of outlier rejection setups [21].
Li et al. [18] used an area-based maximum selection rule to determine which of the input is likely to contain the most useful information by considering the maximum absolute variance value of the central coefficients within a window.
The evaluation function based on image gray gradient is the most widely used definition evaluation function, which includes absolute variance function, Roberts gradient summation function, Brenner function, power function, variance function, Laplacian function, and Tenengrad function, etc. [17].
As we found no difference across ethnicities in residual variance in intelligence once deletion length was controlled, it remains possible that total absolute variance in FSIQ associated with non-genetic factors does not differ across groups.
Consequently, it is problematic to compare absolute variance measurements directly between FACS and microscope.
All selected genes are presented in Supplementary Table 1 (sorted according to absolute variance-fold values).
Relevant genes were selected using different criteria: (a) a significance level of P ≤ 0.05 (Bonferroni/Holm corrected Brown-Forsythe version of the Levene test) for variance-fold values and (b) a cutoff value for absolute variance-fold levels of greater than 2.5 for higher variances in RA, OA, and NC, respectively.
The arrays were preprocessed using the popular RMA algorithm for background correction followed by quantile normalisation (see methods), however not performing any background correction resulted in a similar relative variance pro le but noticeably reduced absolute variances (Additional File 1).
Alternatively, in the unsupervised analysis mode, three feature rankings are obtained from the pathway expression variance matrix (rows = pathways, columns = samples) by computing the absolute variances across the columns/samples, the magnitude of the loadings in a sparse principal component analysis (Zou and Hastie, 2008) and a recently proposed entropy score (Varshavsky et al., 2006).
Meliosma sp. Sabiaceae ST 1 0.2 1.5 0.119 O Total for all species 104 767.7 156496 300.0 The dispersion of species is denoted as: U for uniform (63 species), R for random (no species), C for clumped (23 species) and O for obscure (37 species with a single occurrence and absolute zero variance).
