Identifying domain-general and domain-specific predictors of low mathematics performance: A classification and regression tree analysis

open access: yesJournal of Numerical Cognition, 2017
Many children struggle to successfully acquire early mathematics skills. Theoretical and empirical evidence has pointed to deficits in domain-specific skills (e.g., non-symbolic mathematics skills) or domain-general skills (e.g., executive functioning and language) as underlying low mathematical performance.

Technical Analysis Techniques versus Mathematical Models: Boundaries of Their Validity Domains [PDF]

open access: yes, 2006
We aim to compare financial technical analysis techniques to strategies which depend on a mathematical model. In this paper, we consider the moving average indicator and an investor using a risky asset whose instantaneous rate of return changes at an unknown random time. We construct mathematical strategies.
