Suitability of Multiple Correspondence Analysis for a database exploration before inference analysis. Example with a driving simulator based study.

In most human component system studies performed in simulators, several factors (at least two, i.e. individual and time) and many variables are present. This article suggests starting the analysis while keeping both the multifactorial (MF) and multivariate (MV) aspects. To achieve this aim, with the possibility to show nonlinear relationships, a MFMV exploration of the experimental database is performed using the pair (fuzzy space windowing, Multiple Correspondence Analysis). Then may come an inference analysis. This long (due to multiple large graphical views) but rich procedure is illustrated and discussed using a car driving study example.
