Welcome to the new homepage of the Multifactor Dimensionality Reduction (MDR) open-source software package.

MDR is a data mining strategy for detecting and characterizing nonlinear interactions among discrete attributes (e.g. SNPs, smoking, gender, etc.) that are predictive of a discrete outcome (e.g. case-control status). Just like professional essay writer free online providing you with writing strategies, we're here to provide you with data mining strategies. .  The MDR software combines attribute selection, attribute construction and classification with cross-validation to provide a powerful approach to modeling interactions. The same level of professionalism you can find at, if you need to order a research paper.
