Objectives
1. Introduction to chemometrics, basic ideas, terms, methods, techniques, examples
2. Elements of mathematical statistics (random variables, distribution function, expectation value, variance, hypothesis testing, examination of normality, etc.).
3. The black box model and its usage (empirical, “statistical” modeling, choosing variables (factors). The correlation coefficient and its variants (COD = coefficient of determination), their abuse.
4. Curve fitting, ANOVA, regression (linear and non-linear case, model discrimination, checking the linearity, detection of trends etc., most frequent errors in regression and how to avoid them).
5. Multivariate techniques 1: Multiple linear regression, forward selection, backward elimination, best subset, (F test, t test), LFER, QSAR, examples.
6. Multivariate techniques 2: Pattern recognition 2. Principal Component Analysis, Factor Analysis. How and when to use them?
7. Multivariate techniques 3: Pattern recognition (supervised and unsupervised) 1. Hierarchical Cluster analysis, an example.
8. Linear discriminant analysis, wine and olive oil authentication.
9. Comparison of methods and models by consensus. Sum of ranking differences. Examples. Features of SRD ordering. methods of data fusion.
10. Cross- or external validation? Variants of cross-validation (LOO, LMO, bootstrap Monte Carlo, permutation test).
11. Discrimination of seemingly equivalent variables. The Pair-wise Correlation Method and its generalization.
12. How can multivariate data analysis be useful for chromatographers? (Abraham and Snyder’s models, comparison of column classification systems: Wilson’s, Euerby’s, Hoogmartens’ and Poole’s).
13. Determination of pseudorank (number of latent variables, principal components). SRD ordering in case of repeated observations.
14. Practice, analysis of students’ data sets; exam.
