[Data exploration using post-factorial analysis: use of structured data interrogation software].
The language for interrogating data (LID) allows the graphical and numerical exploration of a cloud of points resulting from a factorial analysis. The interest of a post-factorial analysis in epidemiology is shown in the present paper: a measure of the department effect; a measure of year effect; an assessment of the adjustment on one factor in the framework of a survey on the risk factors of milk quality.
