Bi-directional prospective associations between objectively measured physical activity and fundamental motor skills in children: a two-year follow-up

International Journal of Behavioral Nutrition and Physical Activity, 2020
Background The direction of the longitudinal relationship between physical activity (PA) and fundamental motor skills (FMS) remains unclear. We evaluated the bi-directional, prospective relationships between intensity-specific physical activity (PA) and ...

Control Variates for Probability and Quantile Estimation [PDF]

, 1997
In stochastic systems, quantiles indicate the level of system performance that can be delivered with a specified probability, while probabilities indicate the likelihood that a specified level of system performance can be achieved.

Spread Option Pricing Under Finite Liquidity Framework

Risks
This work explores a finite liquidity model to price spread options and assess the liquidity impact. We employ Kirk approximation for computing the spread option price and its delta.

Maximizing Banking Profit on a Random Time Interval

Journal of Applied Mathematics, 2007
We study the stochastic dynamics of banking items such as assets, capital, liabilities and profit. A consideration of these items leads to the formulation of a maximization problem that involves endogenous variables such as depository consumption, the ...

Regression-Based Methods for Using Control and Antithetic Variates in Monte Carlo Experiments [PDF]

Methods based on linear regression provide a very easy way to use the information in control and antithetic variates to improve the efficiency with which certain features of the distributions of estimators and test statistics are estimated in Monte Carlo

Efficient sequential Monte Carlo with multiple proposals and control variates

, 2016
Sequential Monte Carlo is a useful simulation-based method for on-line filtering of state space models. For certain complex state space models, a single proposal distribution is usually not satisfactory and using multiple proposal distributions is a ...

Variations in Access Control Logic [PDF]

, 2008
In this paper we investigate the design space of access control logics. Specifically, we consider several possible axioms for the common operator says . Some of the axioms come from modal logic and programming-language theory; others are suggested by ideas from security, such as delegation of authority and the Principle of Least Privilege.
