  skos:definition "L'analyse factorielle, sous-famille de l'analyse multivariée, regroupe différentes méthodes conçues pour analyser des tableaux de données complexes. L'objectif : mettre en évidence l'existence ou l'absence de facteurs d'influence entre les variables, et les hiérarchiser. (Adapté de : <a href=\"https://blog.hubspot.fr/marketing/analyse-factorielle\">https://blog.hubspot.fr/marketing/analyse-factorielle</a>)"@fr, "Factor analysis is a statistical method used to describe variability among observed, correlated variables in terms of a potentially lower number of unobserved variables called factors. For example, it is possible that variations in six observed variables mainly reflect the variations in two unobserved (underlying) variables. Factor analysis searches for such joint variations in response to unobserved latent variables. The observed variables are modelled as linear combinations of the potential factors plus \"error\" terms, hence factor analysis can be thought of as a special case of errors-in-variables models.Simply put, the factor loading of a variable quantifies the extent to which the variable is related to a given factor. A common rationale behind factor analytic methods is that the information gained about the interdependencies between observed variables can be used later to reduce the set of variables in a dataset.
