Sentence examples for normalization transformation from inspiring English sources

Several variance-stabilization and normalization transformation methods, which try to transform expression values to be equal variance and normally distributed for each gene, have been proposed [ 19- 23].

To remove sources of systematic variation due to experimental artifacts in the measured intensities and to ensure that the usual assumptions for statistical inferences are met (normality, homoscedasticity), we applied a variance stabilization and normalization transformation on the variables (peptides).

Low-level analysis refers to pre-processing of methylation data (i.e. normalization, transformation and filtering), whereas high-level analysis is focused on illustrating the application of the widely used class comparison, class prediction and class discovery methods to DNA methylation data.

First, to compare between the three variables studied here, we performed the following normalization transformation: X t) = frac{{x t) - bar{x}}}{{sigma_{x} }}.

here denotes the global normalization transformation resulting from the combination of translation, rotation, scaling, and reflection.,, denote, respectively, the "3D-to-2D" parallel projections on the,, and canonical 2D planes.

Our data integration approach includes microarray data normalization, transformation, and quality control.

After normalization and transformation, a one-point increase in log2-transformed value corresponds to a doubling of mRNA expression.

Quackenbush, J. Microarray data normalization and transformation.

The collated earthworm array dataset was imported without any further normalization or transformation.

Background correction, between-array normalization and transformation were carried out using the VSN method for variance stabilization and calibration of microarray data.

After spatial normalization, a transformation file was obtained and stored.
