Sentence examples for variance in data from inspiring English sources

PCR and PLS methods involve the decomposition of the experimental data, such as spectrofluorimetric data in this case, into systematic variations (principal components or factors) that explain the observed variance in data.

PCA helps to explain the variance in data and is a common technique for dimensionality reduction in high dimensional data.
