Titolo: Data thinning and beyond
Abstract: Contemporary data analysis pipelines often involve the use and reuse of data. For instance, a scientist may explore a dataset to select an interesting hypothesis, and then wish to test this hypothesis with the same data. From a statistical perspective, this double use of data is highly problematic: it induces dependence between the hypothesis generation and testing stages, which complicates inference. Failure to account for this dependence renders classical inference techniques invalid.
I will present "data thinning", a set of strategies for obtaining independent training and test sets so that the former can be used to select a hypothesis, and the latter to test it. Data thinning enables valid selective inference in settings for which no solutions were previously available. However, it is also restrictive, in the sense that it requires strong distributional assumptions. Therefore, I will also present strategies inspired by data thinning that enable valid post-selection inference without such assumptions.

Dear all,
This is a reminder that the deadline for registration (*2026-01-07*) for
the *DeFi & Crypto Workshop*, which will be held at Scuola Normale
Superiore (Pisa, Italy) *from 26/01/2026 to 28/01/2026*, is approaching.
The workshop explores key policy, technological, and market dynamics of the
crypto ecosystem, with a focus on DeFi mechanisms, market microstructure,
risk, and price formation.
The program features nine invited talks by leading academics and industry
experts, complemented by contributed sessions highlighting current trends
and future challenges in DeFi. For more information please refer to
the official
website <https://sns-defi.github.io/>.
Best regards,
DeFi & Crypto Workshop Organizing Committee
