Chemometrics is an interdisciplinary field within the sciences that uses statistics, algorithms, and mathematical models to extract and analyze information from chemical data. Due to its nature, chemometrics is often referred to by several synonyms. One such synonym is chemical informatics, which describes its focus on data analysis and information processing in chemistry. Another widely used term is chemoinformatics, which refers specifically to the use of algorithms and computational methods to analyze and model chemical data. Chemometrics is also related to mathematical chemistry, a branch of theoretical chemistry that uses mathematical models to describe and understand chemical phenomena. In summary, these terms all refer to the use of mathematical and computational methods to analyze and extract information from chemical data sets.
