In this essay, @JoseGoldim and I go for some ethical thoughts on post-publication correction mechanisms, particularly about about a special case of retractions - the ones non-attributable to authors. Glad to share with you. https://t.co/MW2L2lT7i1

"Statistics is a branch of Math." Nope. Statistics heavily uses math but isn't just math. Even for a very basic statistical concept like the p-value, the main challenges with applying it are philosophical and sociological, not the mathematics which is pretty straightforward.

Of major concern!!

Se há um dos conceitos mais difíceis em epidemiologia diz respeito à distribuição dos fatores de risco e dos desfechos em nível populacional e das intervenções populacionais. As passagens de Geoffrey Rose são… indigestas. #epitwitter
