Modern social network analysis---the analysis of relational data arising from social systems---is a computationally intensive area of research. Here, we provide an overview of a software package which provides support for a range of network analytic functionality within the R statistical...

Effective memory structures for relational data within R must be capable of representing a wide range of data while keeping overhead to a minimum. The network package provides an class which may be used for encoding complex relational structures composed a vertex set together with any...

The decision-making strategies of pilots were examined using a linear modeling technique. Three hundred twenty-six American, 104 Norwegian, and 51 Australian pilots completed a scenario-based judgment task in which they assigned a comfort rating to each of 27 weather scenarios for each of three...

type="main" xml:id="insr12027-abs-0001" <p>The paper by Lange, Chi and Zhou (hereafter ‘the authors’) serves not only as a useful reminder about the importance of optimization techniques in implementing modern statistical methods but also as a collection of various techniques along with...</p>

The mixtools package for R provides a set of functions for analyzing a variety of finite mixture models. These functions include both traditional methods, such as EM algorithms for univariate and multivariate normal mixtures, and newer methods that reflect some recent research in finite mixture...
