Optimal nonparametric testing of Missing Completely At Random, and its connections to compatibility
Thomas B Berrett, Richard J Samworth
Given a set of incomplete observations, we study the nonparametric problem of testing whether data are Missing Completely At Random (MCAR). Our first contribution is to characteris…
Discussion of 'Multivariate Fisher's independence test for multivariate dependence'
Thomas B Berrett
Invited discussion for Biometrika of 'Multivariate Fisher's independence test for multivariate dependence' by Gorsky and Ma (2022).
Goodness-of-fit testing for Hölder continuous densities under local differential privacy
Amandine Dubois, Thomas Berrett, Cristina Butucea
We address the problem of goodness-of-fit testing for Hölder continuous densities under local differential privacy constraints. We study minimax separation rates when only non-inte…
Locally private online change point detection
Thomas Berrett, Yi Yu
We study online change point detection problems under the constraint of local differential privacy (LDP) where, in particular, the statistician does not have access to the raw data…
Strongly universally consistent nonparametric regression and classification with privatised data
Thomas Berrett, László Györfi, Harro Walk
In this paper we revisit the classical problem of nonparametric regression, but impose local differential privacy constraints. Under such constraints, the raw data $(X_1,Y_1),\ldot…
Locally private non-asymptotic testing of discrete distributions is faster using interactive mechanisms
Thomas B. Berrett, Cristina Butucea
We find separation rates for testing multinomial or more general discrete distributions under the constraint of local differential privacy. We construct efficient randomized algori…
