We will be thinking dreaming and breathing statistics in this volume To ensure we retain a balanced perspective on life I refer you to the famous American Robert Frost s well known poem The Road Not Taken see end of this article With apologies to Robert Frost rather than focusing on roads not taken we shall brie y consider instead roads we have taken or The Roads Traveled over the year journey ...

By explicitly taking into account the effects of vibration-induced dipole-dipole interactions between periodic supercells, we derive an efficient formulation to calculate the phonon frequencies of an ionic crystal. We demonstrate that the vibration-induced dipole-dipole interactions lead to a constant contribution to the interatomic force constant in real space. It recovers the result of Cochra...

We propose a Cochran-Armitage-type and a score-free global test that can be used to assess the presence of an association between a set of ordinally scaled covariates and an outcome variable within the range of generalized linear models. Both tests are developed within the framework of the well-established 'global test' methodology and as such are feasible in high-dimensional data situations un...

Periodontal diseases are inflammatory diseases of the supporting structures of the teeth (Cochran, 2008; Kornman, 2008). They are initiated by periodontopathic bacteria and result in progressive destruction and loss of the periodontium (Cochran, 2008; Kornman, 2008). Progression of periodontal disease eventually leads to tooth loss (Chambrone, et al., 2010). Periodontal diseases are multifactor...
