Khan Academy The Triple Helix [citation needed]» Blog Archive » large-scale data exploration, MIC-style UPDATE 2/8/2012: Simon & Tibshirani posted a critical commentary on this paper here. See additional thoughts here. Real-world data are messy. Relationships between two variables can take on an infinite number of forms, and while one doesn’t see, say, umbrella-shaped data very often, strange things can happen. When scientists talk about correlations or associations between variables, they’re usually referring to one very specific form of relationship–namely, a linear one. The assumption is that most associations between pairs of variables are reasonably well captured by positing that one variable increases in proportion to the other, with some added noise. Detecting a non-linear association is potentially just as easy as detecting a linear relationship if we know the form of that association up front. To give you an intuitive sense of how this works, consider this Figure from the supplemental material: The underlying function here is sinusoidal.

The OpenScience Project | Open source scientific software C’est la faute aux « fact-checkeurs », ces journalistes importuns Ouf ! On vient enfin de trouver le coupable. Qui est responsable de la dégradation du débat politique ? Stéphane Soumier, journaliste à BFM Business, a trouvé la réponse : les « fact-checkeurs ». Quelle importance, que les chiffres soient exacts ou approximatifs ? « L’économie n’est jamais statique, elle est dynamique, et la dynamique ne se “fact-check” pas, elle dépend de la volonté des hommes. » L’argumentaire mérite d’être examiné (je n’ose pas dire « fact-checké »). Le pouvoir médiatique, jusqu’à preuve du contraire, est encore incarné par le duo mutique Pujadas-Ferrari, à qui il fut interdit d’arbitrer entre les chiffres balancés à tort et à travers par les deux candidats, tandis que sur la Toile, oui, s’échinaient quelques factcheckeurs. On n’y est pas. Soumier a pourtant le mérite (et l’honnêteté) d’exprimer tout haut ce que nombre de journalistes pensent tout bas. La presse généraliste française est une presse d’idées, pas de chiffres.
