Skin-to-skin contact and breastfeeding practices in Nigeria: a study of socioeconomic inequalities

International Breastfeeding Journal, 2022
Background The effects of breastfeeding practices on children’s health are undoubtedly of great interest. However, inequalities in breastfeeding practices and mother and newborn skin-to-skin contact (SSC) exist in many resource-constrained settings. This

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

BMC 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

SSM: 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.

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

IEEE 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 $Q$ .

Matrix Poincaré inequalities and concentration [PDF]

Advances in Mathematics, 2020
We show that any probability measure satisfying a Matrix Poincaré inequality with respect to some reversible Markov generator satisfies an exponential matrix concentration inequality depending on the associated matrix carré du champ operator. This extends to the matrix setting a classical phenomenon in the scalar case. Moreover, the proof gives rise to

Compound Poisson point processes, concentration and oracle inequalities

Journal 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).

Tensor Concentration Inequalities: A Geometric Approach

Symposium on the Theory of Computing
Matrix concentration inequalities, commonly used in the forms of non-commutative Khintchine inequalities or matrix Chernoff bounds, are central to a wide range of applications in computer science and mathematics.

A Copula-Based Piecewise Health Concentration Curve for Modeling Stress-Related Performance Inequalities [PDF]

Tutorials in Quantitative Methods for Psychology
Health concentration curves are essential tools for quantifying inequalities in health outcomes across socioeconomic or biological gradients. In this study, we propose a novel copula-based piecewise health concentration curve constructed with the gluing ...
