Testing for Nonlinearity in Mean in the Presence of Heteroskedasticity [PDF]
, 2004 This paper considers an important practical problem in testing time-series data for nonlinearity in mean. Most popular tests reject the null hypothesis of linearity too frequently if the the data are heteroskedastic. Two approaches to redressing this size distortion are considered, both of which have been proposed previously in the literature although ...

Presence and mediated interaction: A means to an end?
2009Promoting a sense of presence is often identified as a prerequisite for mediated interaction. To do so, however, we need a thorough understanding of what presence encompasses and how it can be influenced. The goal of this paper is to elaborate on the different aspects of the sense of presence as identified in the literature, while illustrating whether ...
