Risk factors for suicidal tendency in people with epilepsy in China: a case–control study
Scientific Reports, 2021 People with epilepsy (PWE) have an increased suicide prevalence. This study aimed to identify the risk factors for suicidal tendency among PWE in West China. A nested case–control study was designed in a cohort of patients with epilepsy (n = 2087).

Truncated control variates for weak approximation schemes*
ESAIM: Proceedings and Surveys, 2017 In this paper we present an enhancement of the regression-based variance reduction approaches recently proposed in Belomestny et al. [1] and [4]. This enhancement is based on a truncation of the control variate and allows for a significant reduction of ...

Automatic control variates for option pricing using neural networks
Monte Carlo Methods Appl., 2021 Many pricing problems boil down to the computation of a high-dimensional integral, which is usually estimated using Monte Carlo. In fact, the accuracy of a Monte Carlo estimator with M simulations is given by σM{\frac{\sigma}{\sqrt{M}}}. Meaning that its

On the optimal control for variational inequalities [PDF]
Journal of Optimization Theory and Applications, 1976 We prove an existence theorem for the optimal control of variational inequalities governed by a pseudomonotone operator: the cost is assumed to be quadratic. Then, we give an extension of the theorem to more general costs (assuming the operator to be monotone); we also give a result on a perturbation problem.

Vector-Valued Control Variates
, 2021 Control variates are variance reduction tools for Monte Carlo estimators. They can provide significant variance reduction, but usually require a large number of samples, which can be prohibitive when sampling or evaluating the integrand is computationally expensive.
