The obtained spatially normalized tissue class images of each subjects are averaged and used as prior probabilities for each voxel to belong to a particular tissue class (Ashburner and Friston 2005).
In other words, all 'nerve voxels' falling, according to their signal intensities into normalized bin classes, >1.2 were classified as 'nerve-lesion-voxels'.
We intentionally made no assumptions on a certain threshold of normalized bin classes to serve as cut-off value for binary classification ('nerve lesion voxels' versus 'non-lesion nerve voxels'non-lesion nervethreshold that best provoxelsa separation butween the three groups.
To account for the variation in allelic coverage in the D. melanogaster genomes, Tajima's D (Tajima 1989) was calculated as the sum of Tajima's D for each allelic coverage class normalized by the square root of the number of allelic classes.
For example, one study estimated that to achieve 50% overlap in prognostic gene sets for breast cancer patients would require several thousand samples (Ein-Dor et al. 2006), and other work created a general tool to calculate the number of samples needed to train a classifier as a function of normalized fold change, class prevalence, and the number of genes on an array (Dobbin et al. 2008).
We demonstrate that the application of cross-class normalized to dependent paired data increases the distance between the objects of two classes and decreases the number of misclassification errors.
The notations S ∗ : = S 1 ∗ and C : = C 1 are well known, where S ∗ and C represent, respectively, the class of normalized starlike and normalized convex functions in the unit disc U.
