[Multivariate analysis used in the investigation of antimicrobials].

Multivariate analysis techniques are reviewed. The study of variables requires special methods with two precise objectives, the simultaneous analysis of all the inputs and logical support when making decisions. The most common descriptive and explanatory techniques are discussed. The seven common steps usually developed for multivariate tests implementation are shown. The creation of an advisory board for methodology used by research entities is proposed for the rational control and performance of research processes. The need for more inventors, as well as more financial assistance for researchers, is highlighted.
