Sentence examples for systematic sources of variation from inspiring English sources
A normalisation method was used to compensate for systematic sources of variation in gene expression measurements.
To remove systematic sources of variation, we used a within-print group scaled normalization method (Yang et al. 2002).
The distribution of standard deviations for both the low- and high-abundant data are shifted higher than for other systematic sources of variation indicating greater variability in disagreement.
When measured, the confounding generated by these systematic sources of variation can be controlled by correcting for them in a model.
Systematic sources of variation can often be tackled via careful study design; for example, by balancing and/or randomising treatment arms over potentially confounding variables (such as plates or batches, or having multiple observers/experimenters involved in data collection).
Other factors not directly considered here (e.g., fasting time, time of day, time since last void) may also have impacts on UFR that should be assessed for systematic sources of variation in interpretation of biomarker concentrations.
Calibration of microarray measurements thus aims at removing consistent and systematic sources of variations to allow mutual comparison of measurements acquired from different probes, arrays and experimental settings.
Overlay error has been considered as a systematic source of variation; however, it is segueing into a random error for technology nodes smaller than 45-nm.
Overall, however, white blood cell distributions explained a relatively small proportion of the variability in patterns of cord blood DNA methylation associated with in utero exposure to arsenic (3% for total U-As), so the remaining systematic source of variation was hypothesized to be alterations to the methylome itself in some or all of the cell populations examined.
Like all microarrays, Affymetrix SNP arrays are affected by systematic sources of experimental variation.
For example, systematic sources of perturbation such as naturally occurring genetic variation in a population or specific drug perturbations in which response is observed over time can lead to reliable causal inference [ 1, 2, 18, 19].
