This course presents the statistical methods exploited in data analysis (factor analysis) or in modeling the explanatory relation of a response variable (regression) and their use in the pyramid of business intelligence. The first part of the course is devoted to the factorial analysis which, by confronting the representation spaces of individuals and variables, enriches the interpretation and makes it possible to exhibit the internal structure of the data. The data nature and coding lead to two essential variants of factorial methods, namely Principal Component Analysis (PCA) and Multiple Correspondence Analysis (MCA), combined in Multiple Factor Analysis (MFA). The second part presents different regression models and methods for estimating their parameters, from the linear model to more complex models with ill-known structure or suitable for unusual data distribution.
