The problem, Statistical Inference within the 21st Century: A World Past P

Containing 43 papers by statisticians from all over the world, the particular concern is anticipated to result in a serious rethinking of statistical inference by initiating a course of that finally strikes statistical science—and science itself—into a brand new age.

“The statistical neighborhood has not but converged on a easy paradigm for the usage of statistical inference in scientific analysis—and actually it might by no means achieve this,” they acknowledge. “A one-size-fits-all method to statistical inference is an inappropriate expectation. As an alternative, we advocate scientists conducting statistical evaluation of their outcomes ought to undertake what we name the ATOM mannequin: Settle for uncertainty, be Considerate, be Open, be Modest.”
