  Chemometrics - Wikipedia, the free encyclopedia
Chemometrics is the application of mathematical or statistical methods to chemical data.
Chemometrics is the science of relating measurements made on a chemical system or process to the state of the system via application of mathematical or statistical methods.

 An Introduction to Chemometrics, by Brian A. Rock, Ph.D.
Chemometrics itself can be defined as the application of mathematical, statistical, graphical or symbolic methods to maximize the chemical information which can be extracted from data.
One of the primary goals of chemometrics is to reduce the number of dimensions needed to accurately portray the characteristics of the data set.
In some sense, most chemometric techniques are statistical in nature; a separate statistical category serves as a catch-all for those techniques which don't comprise a category of their own in chemometrics.

 Chemometrics
Chemometrics is the field of extracting information from multivariate chemical data using tools of statistics and mathematics.
The goal of chemometric regression analysis is to develop a calibration model which correlates the information in the set of known measurements to the desired property.
Chemometric algorithms for performing regression include partial least squares (PLS) and principal component regression (PCR) and are designed to avoid problems associated with noise and correlations in the data.
