MULTIVARIATE ANALYSIS OF SPECTROSCOPIC DATA
Advanced chemometric strategies for conservation science
A summary of the course
Objectives
- Acquisition of basic knowledge for the selection and application of suitable row and column pretreatments
- Acquisition of basic knowledge regarding supervised chemometric methods
- Acquisition of skills for the interpretation of graphical and numerical outputs
- Acquisition of practical skills in the use of CAT chemometric software
Description
This course, held in English in its second edition, will introduce participants to the fundamentals of chemometrics, with special reference to multivariate analysis methods aimed at extracting maximum information from analytical data of spectroscopic nature in the context of cultural heritage research. Strategies for the pretreatment of spectral profiles and principal component analysis (PCA) will be covered in detail and basic notions on supervised methods of multivariate classification and regression will be provided. The illustration of theoretical and descriptive aspects will be supported by the discussion of a variety of applications in the cultural heritage field. This will be followed by a specific module dedicated to practical demonstrations and guided practice on the use of a free software (CAT) that will be made available to all participants.
