Sunday, November 12; 8:30am – 5:00pm
Dr. Donald Dahlberg, Lebanon Valley College (Emeritus), Annville, PA
Dr. Barry Wise, Eigenvector Research, Wenatchee, WA
This introductory course concentrates on two areas of chemometrics: (1) exploratory data analysis and pattern recognition, and (2) regression. Participants learn to apply techniques such as Principal Component Analysis (PCA), SIMCA, Principal Component Regression (PCR), and Partial Least Squares regression (PLS) safely. The most commonly used methods of outlier detection and data pretreatment with also be illustrated. An emphasis will be put on understanding the chemometric process without having to learn matrix algebra. This course can be combined with Intermediate Chemometrics Without Equations for a two-day course (E15-03). A discount will be offered over separately registering for the two one-day courses.
WHO SHOULD ATTEND
This course on Chemometrics without Equations (or Hardly Any) is designed for those who wish to explore the problem-solving power of chemometric tools, but are discouraged by the high level of mathematics found in many software manuals and texts. Course emphasis is on proper application and interpretation of chemometric methods as applied to real-life problems. The objective is to teach in the simplest way possible so that participants will be better chemometrics practitioners and managers.

ABOUT THE INSTRUCTORS
Dr. Donald Dahlberg (Course Director) is Professor Emeritus of Chemistry at Lebanon Valley College. Dr. Dahlberg earned a B.S. in Chemistry from the University of Washington and a Ph.D. in Physical Chemistry from Cornell University. After decades of doing research in the area of Physical Organic Chemistry, he got involved in Chemometrics while on sabbatical in 1988 at the Center for Process Analytical Chemistry at Washington. There he learned chemometrics in the Bruce Kowalski group (co-founder of chemometrics). Upon returning to LVC, he taught chemometrics to undergraduate students for over a decade. Although retired from the classroom, he continues to do consulting and supervises undergraduate research in industrial chemistry. Dr. Dahlberg wrote and teaches this course so that those not fluent in matrix algebra can take advantage of the powerful tool of chemometrics.
Dr. Neal B. Gallagher, PLS_Toolbox co-author and co‐founder of Eigenvector Research, Inc., holds a doctorate in Chemical Engineering and has experience in a wide variety of applications spanning chemical process monitoring, hyperspectral image analysis, anomaly detection, quantification and classification, regression modeling and analytical instrumental development. He has extensive teaching experience including Eigenvector University and dozens of chemometric courses.
