Stock return predictability: Evidence from moving averages of trading volume

Pacific-Basin Finance Journal, 2021
This study investigates the role of moving averages of trading volume on asset pricing. We find that the distance between short- and long-term moving averages of trading volume (MAVD) strongly and negatively predicts the cross-section of stock returns in

Moving Weighted Averages

Canadian Journal of Mathematics, 1993
AbstractLet ℝ denote the real line. Let {Tt}tєℝ be a measure preserving ergodic flow on a non atomic finite measure space (X, ℱ, μ). A nonnegative function φ on ℝ is called a weight function if ∫ℝ φ(t)dt = 1. Consider the weighted ergodic averagesof a function f X —> ℝ, where {θk} is a sequence of weight functions. Some sufficient and some necessary

Calculating acute:chronic workload ratios using exponentially weighted moving averages provides a more sensitive indicator of injury likelihood than rolling averages

British Journal of Sports Medicine, 2016
Objective: To determine if any differences exist between the rolling averages and exponentially weighted moving averages (EWMA) models of acute:chronic workload ratio (ACWR) calculation and subsequent injury risk.

Memory-type ratio and product estimators for population variance using exponentially weighted moving averages for time-scaled surveys

Communications in statistics. Simulation and computation, 2022
In this study, we have proposed memory-type ratio and product estimators for the estimation of population variance based on exponentially weighted moving averages (EWMA) statistic.
