It is usually better in terms ofboth care and time to allow the flow to come to a natural halt from exhaustion of either the speaker or the material." The first half of this advice (from an experienced advocate and judge in medicolegal cases and a he...

Let the data speak: a response to Terracciano (2014).

Characterising acute coronary syndrome-associated depression: Let the data speak.

Depression in the context of acute coronary syndrome (ACS) is understood to confer increased morbidity and mortality risk. The pathophysiological mechanisms underlying this association remain poorly understood, although several candidates including inflammation, cardiac autonomic dysregulation, and behavioural factors are viewed as of key importance. No single bio-behavioural explanatory model ...

Let the Shape Speak - Discriminative Face Alignment using Conjugate Priors

This work presents a novel Bayesian formulation for aligning faces in unseen images. Our approach is closely related to Constrained Local Models (CLM) [2] and Active Shape Models (ASM) [6], where an ensemble of local feature detectors are constrained to lie within the subspace spanned by a Point Distribution Model (PDM). Fitting a model to an image typically involves two steps: a local search u...

SUGI 28: Let the Data Speak: New Regression Diagnostics Based on Cumulative Residuals

Residuals have long been used as the basis for graphical and numerical examination of the adequacy of regression models. Conventional residual analysis based on plotting raw residuals or their smoothed versions is highly subjective, whereas most goodness-offit tests provide little information about the nature of model inadequacy. In this paper, new model-checking techniques of Lin et al. (1993,...
