Bruce Kowalski is recognized by the scientific community as the founder of the field of chemometrics. This Symposium Series text is a follow up to the Symposium Series Volume 52 (Chemometrics: Theory and Application), edited by Bruce Kowalski. All major areas in the field are well represented in this book: pattern recognition, library searching, multivariate calibration, multivariate curve resolution, variable selection, data fusion, calibration transfer,
environmental chemometrics, forensics, and biological and mixture analysis. Many chapters have a link to previous work done by Bruce and will serve as a retrospective to the career of Bruce Kowalski, who believed that a rational approach was needed to improve both the quality of measurements and to extract
information from them.

This text will be of interest to individuals who are interested in modeling data. Interest in modeling data continues to grow with the emergence of new areas such as computational statistics, business intelligence, big data, and analytics. In chemistry, modeling of data has taken a different path as it has become integrated into the field of analytical chemistry. Because chemometrics is not well understood by chemists, this text should prove beneficial and be of great interest to researchers
who need to take advantage of techniques such as principal component analysis, partial least squares, linear discriminant analysis and outlier analysis in their work. This text also highlights changes that have occurred in the field since its origins in the mid-1970's and will serve as a report on the
current state of the art of the field of chemometrics.
