Multivariate Analysis


Know the main statistical techniques for the analysis of multidimensional phenomena, identify the optimal technique in relation to the type of data and the objectives of the analysis, interpret the results appropriately.


Techniques presented: 

Techniques of multivariate statistical analysis for segmentation (cluster analysis), classification (discriminant analysis, decision trees) and for perceptual mapping (factor analysis, correspondence analysis, multidimensional scaling).


There are exercises for each of the topics covered.



Attending the TSC course or having knowledge of the topics it contains is preparatory.
