Exploratory multivariate data analysis is studied and teached in a French-way since a long time in France. This course focuses on four essential and basic methods, those with the largest potential in terms of applications: principal component analysis (PCA) when variables are quantitative, correspondence analysis (CA) and multiple correspondence analysis (MCA) when variables are categorical and clustering. An extension to Multiple Factor Analysis (MFA) will give you the opportunity to analyse more complex dataset that are structured by groups.
We hope that with this course, the participant will be fully equipped (theory, examples, software) to confront multivariate real-life data.
This course is application-oriented; formalism and mathematics writing have been reduced as much as possible while examples and intuition have been emphasized and the numerous exercises done with FactoMineR (a package of the free R software) will make the participant efficient and reliable face to data analysis.
This course will be held in English. It has been designed for scientists whose aim is not to become statisticians but who feel the need to analyze the data themselves. It is therefore addressed to practitioners who are confronted with the analysis of data in marketing, surveys, ecology, biology, geography, etc.
An undergraduate level is quite sufficient to capture all the concepts introduced.
Basic knowledges in statistics are necessary, such as: correlation coefficient, chi-squared test, one-way ANOVA.
On the sofware side, an introduction to the R language is sufficient, at least at first.
Participants will focus on one theme per week and will have the opportunity to evaluate their learning progress via a weekly quiz. Each course sequence, will be completed by a series of small quizzes and exercises. You will do your exercises directly in your web browser, and the correctness of your answer will be automatically assessed by the system.
At the end of the course, you will have to complete a final evaluation and participants who have more than 50% of correct answer in quizzes and exercises will receive a certificate of attendance
