  "term": "Parallel factors analysis",
  "field": "Chemistry",
  "definition": "A multi-way decomposition method used in chemometrics to analyze data arrays with three or more modes, such as excitation-emission matrices. It decomposes the data into a set of trilinear components, each representing a pure component's spectral and concentration profiles. This technique assumes trilinearity of the data and provides unique solutions under certain conditions.",
