agefederico ANOVA-SCA (ASCA) and Multilevel-SCA (MSCA).

Analytical chemistry, especially in the context of multidisciplinary applications, has been witnessing an increase in problems where multivariate profiles are collected as a result of designed experiments. Metabolomics and the other –omics disciplines are the domain of election, but problems of such kind are emerging more and more often in food and environmental chemistry or ecotoxicology, just to cite a few. To deal with these issues, specific multivariate tools have been proposed: ANOVA-Simultaneous Component Analysis (ASCA) and Multilevel Simultaneous Component Analysis (MSCA) are generalizations of (M)ANOVA fixed-effect models for high-dimensional data, which are being increasingly used in different areas of chemometrics and -omics.

The course will provide an introduction to the theory and application of these tools and it will be articulated along the following outline:

  1. Introduction to the theory of linear models.
    Factorial designs: fixed vs random effects; crossed, nested, replicated measurements and mixed designs. Contrasts, calculation of the effects and testing (45 minutes).
  2. Generalization to high-dimensional data from crossed –designs.
    ANOVA-SCA (ASCA): model and calculation of the effect matrices. Validation of the significance of the effects. Interpretation of the model. Graphical tools (60 minutes).
  3. Generalization to high-dimensional data from nested –designs.
    Multilevel-SCA (MSCA): model and calculation of the effect matrices. Validation of the significance of the effects. Interpretation of the model. Graphical tools. Supervised modeling of the within group variation (Multilevel-PLSDA) (60 minutes).

All ideas will be illustrated with real-life examples from chemistry and metabolomics.

joaquimannadejuan Multivariate Curve Resolution (MCR).
The course will be a combination of theoretical concepts and hands-on work around the topic of Multivariate Curve Resolution, particularly the description and the use of the MCR-Alternating Least Squares (MCR-ALS) algorithm. There will be explanations on how to work with single data sets and multiset structures (formed by several data tables together). Recent variants of MCR incorporating hard-modeling information (e.g., kinetic laws,..) and calibration tasks (correlation constraint) will also be described. Practical examples will include analytical data (chromatography, processes,…)  and hyperspectral images. Theory and hands-on work will be combined during the course.
  • MCR. Basic concept. MCR-ALS algorithm. Constraints.
  • Single data analysis.
  • Multiset analysis.
Documentation, software and data sets will be provided.
Requirements: It is recommended that attendants have some basic background in multivariate data analysis. Since practical work will be done, bringing a laptop is necessary to follow adequately the course. MATLAB is recommended, but not compulsory. The GUI interface provided can run under MATLAB environment or as a stand-alone in the compiled form.

beata Data preprocessing.
Data analysis is a multistage process. All its elements are equally important and decide about final results and conclusions. There are strict rules concerning sampling (in a case of natural products), experimental design, data modeling, and results validation. There are not, however, any rules concerning data pre-processing. The preprocessing step usually involves preprocessing of individual signals (signals enhancement via signals de-nosing and background elimination), as well as preprocessing of the signal set (signal transformations, normalization, alignment, etc.). All steps of data pre-processing are data dependent and they should be based on data characteristics. An influence of different data noise types, different normalization methods, different transformations, etc., on a final identification of the significant features will be discussed for the real and simulated data sets. Certain diagnostics tools will be introduced to evaluate data properties and simple rules will be proposed concerning an order of the pre-processing steps. Moreover, a comparison of data processing based on peak table and on entire signals (fingerprints) will be presented.

Course duration: 4 hours.

Afternoon courses (14:00–17:45h)
riccardo Introduction to Design of Experiments, DoE
The main goal of this introductory course is to show the participants that Experimental Design is based on the knowledge of the problem much more than on mathematical or statistical formulas.
It will be shown that the key of the success of an Experimental Design is the chemical knowledge, and that the writing of the experimental matrices and the statistical computations can be very easily performed by hand. Under these premises, it will be understood that the specific software (very often not even required) is just a tool, not the center of the procedure.
The main topics treated will be:
  • Why optimizing OVAT (One Variable At a Time) is wrong
  • Full Factorial Designs
  • Plackett-Burman Designs
  • Central Composite Designs

federico Classification methods

Problems involving the classification of samples, i.e., the prediction of a qualitative response, usually associated to the object belonging to group of similar individuals with specified characterstics, is ubiquituous in analytical chemistry and chemometrics. Examples include the authentication of foodstuff, the evaluation of the potential toxicity of a chemical substance, the prognosis or diagnosis of a disease or, in the framework of the –omic disciplines, the identification of predictive biomarkers.
The aim of the course is to provide the attendees with a general introduction to the main classification methods through alternating theory and worked examples in Matlab.
The general outline of the course will be:

  1. Introduction to classification methods.
    What is classification? Classification vs clustering. Discriminant classification vs class-modeling; parametric vs non parametric methods. Classification error and loss function
  2. Discriminant classification methods.
    Linear and quadratic discriminant analysis and their limitation. Partial least squares discriminant analysis (PLS-DA): model building and interpretation of the results.
  3. Class-modeling
    The idea behind class-modeling. The SIMCA methods in its different implementations. Coomans plot
  4. Validation of classification methods
    The need of validating predictive models. Test set vs cross-validation. Double CV and bootstrap.

barry Multivariate Image Analysis.

Intro to Multivariate Image Analysis is designed to give the student practical experience. The course starts with a brief review of principal components analysis (PCA) and partial least squares (PLS) regression and how they are used in image analysis. Tools for exploring multivariate images and performing particle analysis are demonstrated, along with linking of scores in the image plane and in score-score plots. Classification of areas on images is discussed. Additional topics to be covered included multivariate image regression, and preprocessing to capture textural information. Methods to mitigate the effects of background interference, e.g. clutter, will also be discussed. The course includes hands-on computer time for participants to work example problems using PLS_ToolboxMIA_Toolbox, and MATLAB.
