TLDR
This article investigated the developmental predictors of children's fraction concepts and procedures at the end of fourth grade in a 2-year longitudinal study and found that number line estimation, attentive behavior, calculation fluency, and working memory made unique contributions to the acquisition of fraction arithmetic procedures.About:

Association between individual differences in non-symbolic number acuity and math performance: a meta-analysis.
Qixuan Chen,Jingguang Li +1 more
TL;DR: A meta-analysis of cross-sectional and longitudinal studies revealed a moderate but statistically significant association between number acuity and math performance, and suggested that many previous studies were underpowered due to small sample sizes.

From "sense of number" to "sense of magnitude": The role of continuous magnitudes in numerical cognition.
TL;DR: The conclusion is that there is not enough convincing evidence to support the number sense theory anymore, and researchers are encouraged not to assume that number sense is simply innate, but to put this hypothesis to the test and consider whether such an assumption is even testable in the light of the correlation of numerosity and continuous magnitudes.

A meta-analysis of mathematics and working memory: Moderating effects of working memory domain, type of mathematics skill, and sample characteristics
TL;DR: A meta-analysis of 110 studies with 829 effect sizes found a significant medium correlation of mathematics and WM, r =.35, 95% confidence interval [32,.37] as discussed by the authors.

Early predictors of middle school fraction knowledge
TL;DR: Analysis of longitudinal data indicated that whole number magnitude knowledge in first grade predicted knowledge of fraction magnitudes in middle school, controlling for whole number arithmetic proficiency, domain general cognitive abilities, parental income and education, race, and gender.

Why is learning fraction and decimal arithmetic so difficult
TL;DR: This review identifies and discusses two types of difficulties: inherent difficulties of fraction and decimal arithmetic and culturally contingent difficulties that could be reduced by improved instruction and prior knowledge of learners.

A Test of Missing Completely at Random for Multivariate Data with Missing Values
TL;DR: In this article, the authors proposed a global test statistic for multivariate data with missing values, that is, whether the missing data are missing completely at random (MCAR), that is whether missingness depends on the variables in the data set.

Multiple Regression in Behavioral Research: Explanation and Prediction
TL;DR: In this paper, the authors present the foundations of multiple regression analysis and its application in computer science. But, they do not discuss the application in the field of computer science, except for the following:

TL;DR: Tabachnick and Linda S. Fidell as mentioned in this paper reviewed the book, Using Multivariate Statistics by Barbara G. Tabachnick et al., 1983, Vol 28(8), 642.
Journal ArticleDOI
Core systems of number
TL;DR: This work reviews recent behavioral and neuropsychological evidence that these ontogenetically and phylogenetically shared abilities rest on two core systems for representing number, and identifies one system for representing large, approximate numerical magnitudes, and a second system for the precise representation of small numbers of individual objects.
