How Biased Is Your Model? Concentration Inequalities, Information and Model Bias [PDF]

open access: yesIEEE Transactions on Information Theory, 2017
We derive tight and computable bounds on the bias of statistical estimators, or more generally of quantities of interest, when evaluated on a baseline model $P$ rather than on the typically unknown true model $Q$ .

Socioeconomic inequalities in maternal health service utilisation: a case of antenatal care in Nigeria using a decomposition approach

open access: yesBMC Public Health, 2019
Background Antenatal care (ANC) services are critical for maternal health but Nigeria performs poorly in ANC utilisation compared to other countries in sub-Saharan Africa.

Is socioeconomic inequality in antenatal care coverage widening or reducing between- and within-socioeconomic groups? A case of 19 countries in sub-Saharan Africa

open access: yesSSM: Population Health, 2023
Maternal health statistics have improved in many countries in sub-Saharan Africa (SSA). Still, progress remains slow in meeting the Sustainable Development Goals (SDG) targets.

New insights on concentration inequalities for self-normalized martingales [PDF]

open access: yesElectronic Communications in Probability, 2018
We propose new concentration inequalities for self-normalized martingales. The main idea is to introduce a suitable weighted sum of the predictable quadratic variation and the total quadratic variation of the martingale.

Sparse space–time models: Concentration inequalities and Lasso [PDF]

open access: yesAnnales De L Institut Henri Poincare-probabilites Et Statistiques, 2018
Inspired by Kalikow-type decompositions, we introduce a new stochastic model of infinite neuronal networks, for which we establish sharp oracle inequalities for Lasso methods and restricted eigenvalue properties for the associated Gram matrix with high ...

Compound Poisson point processes, concentration and oracle inequalities

open access: yesJournal of Inequalities and Applications, 2019
This note aims at presenting several new theoretical results for the compound Poisson point process, which follows the work of Zhang et al. (Insur. Math. Econ. 59:325–336, 2014).

Decomposition of socioeconomic inequalities in child vaccination in Ethiopia: results from the 2011 and 2016 demographic and health surveys

open access: yesBMJ Open, 2020
Objectives Monitoring and addressing unnecessary and avoidable differences in child vaccination is a critical global concern. This study aimed to assess socioeconomic inequalities in basic vaccination coverage among children aged 12–23 months in Ethiopia.

Nonconventional moderate deviations theorems and exponential concentration inequalities [PDF]

open access: yesAnnales De L Institut Henri Poincare-probabilites Et Statistiques, 2018
We obtain moderate deviations theorems and exponential (Bernstein type) concentration inequalities for "nonconventional" sums of the form $S_N=\sum_{n=1}^N (F(\xi_{q_1(n)},\xi_{q_2(n)},...,\xi_{q_\ell(n)})-\bar F)$.

CONCENTRATION INEQUALITIES FOR GIBBS MEASURES [PDF]

open access: yesInfinite Dimensional Analysis, Quantum Probability and Related Topics, 2011
We are interested in Sobolev type inequalities and their relationship with concentration properties on higher dimensions. We consider unbounded spin systems on the d-dimensional lattice with interactions that increase slower than a quadratic. At first we assume that the one-site measure satisfies a modified log-Sobolev inequality with a constant ...
