Journal of The A merican Statistical Association

Abstract

The JASA was started in 1922, arising out of the old New Series publications of the American Statistical Association. Initially not concerned with statistical methodology per se, there is now a Theory & Methods section to complement the Applications & Case Studies section, along with review articles and book reviews. In substance, the JASA is dominated by theoretical mathematically‐based statistical methodology, although its authors continue to be motivated by real world problems. Articles are for the most part unsolicited, and the Journal appears quarterly.

Understanding Performance and Verbal-Communication of Children with ASD in a Collaborative Virtual Environment

“…Question 5 was used to assess individuals’ improvements in talking with their partners, with participants reporting high levels of perceived improvement in talking with their partners (ASD group is 4.57 out of 5, TD1 group is 4.0 out of 5, and TD2 group is 4.57 out of 5). The Kruskal-Wallis test, a non-parametric method for testing whether two or more independent samples originate from the same distribution (Billard 2005), indicated that there were no significant between-group differences in responses on the self-report questionnaire.…”

Individual versus Social Benefit on the Heterogeneous Networks

“…Our main purpose is to study how heterogeneity of relationships affects the dynamics of the network. We use exponential random graphs [34][35][36][37], which is a powerful tool to study the networks. It is an extension of the statistical mechanics of Boltzmann and Gibbs to the networks.…”
