testCompareR: an R package to compare two binary diagnostic tests using paired data [version 3; peer review: 1 approved, 2 approved with reservations]

Wellcome Open Research
Background Binary diagnostic tests are commonly used in medicine to answer a question about a patient’s clinical status, most commonly, do they or do they not have some disease.

Identifying the True Willingness-To-Pay of Bayesian Respondents in a Dichotomous Choice Contingent Valuation Methodology [PDF]

This paper develops a respondent model of Bayesian updating for a double-bound dichotomous choice (DB-DC) contingent valuation methodology. We demonstrate by way of data simulations that current DB-DC identifications of true willingness-to-pay (WTP) may ...

Diagnostic Use of Testing for Novel Murine Autoantibodies for Sjögren Disease in the Rheumatology Outpatient Setting

Arthritis Care &Research, EarlyView.
Objective The goal was to assess the diagnostic performance of three novel autoantibodies (NA) for Sjögren disease (SjD) by comparing NA prevalence in patients with SjD, other autoimmune rheumatic diseases (ARDs), nonspecific chronic sialadenitis (CS), and controls.

The transcriptomic signature of RacA activation and inactivation provides new insights into the morphogenetic network of Aspergillus niger.

PLoS ONE, 2013
RacA is the main Rho GTPase in Aspergillus niger regulating polarity maintenance via controlling actin dynamics. Both deletion and dominant activation of RacA (Rac(G18V)) provoke an actin localization defect and thereby loss of polarized tip extension ...

Respondent uncertainty in contingent valuation: the case of whale conservation in Newfoundland and Labrador [PDF]

In this paper we investigate the issue of respondent uncertainty in contingent valuation studies while estimating the willingness to pay for a whale conservation program o¤ the coasts of Newfoundland and Labrador.

Association Between Symptomatic Knee Osteoarthritis and Target Glycemic Control in Individuals With Type 2 Diabetes

Arthritis Care &Research, EarlyView.
Objective Knee osteoarthritis (OA) commonly affects individuals with type 2 diabetes (T2DM) and is associated with increased risk of diabetes‐related complications. To better understand potential mechanisms, we examined the association between symptomatic knee OA and glycemic control in individuals with T2DM.

On the Effect of Random Alternating Perturbations on Hazard Rates

, 2006
We consider a model for systems perturbed by dichotomous noise, in which the hazard rate function of a random lifetime is subject to additive time-alternating perturbations described by the telegraph process.

A panel model for predicting the diversity of internal temperatures from English dwellings [PDF]

, 2012
Using panel methods, a model for predicting daily mean internal temperature demand across a heterogeneous domestic building stock is developed. The model offers an important link that connects building stock models to human behaviour.

New Onset of Fibromyalgia After Exposure to a Combat Environment: A Longitudinal Cohort Study

Arthritis Care &Research, EarlyView.
Objective Traumatic life events are hypothesized to be triggers for the onset of fibromyalgia. Posttraumatic stress disorder (PTSD) is a common comorbidity of fibromyalgia. However, limited prospective data are available on the development of fibromyalgia after exposure to high‐magnitude stress.

Comparison of methods to handle missing values in a binary index test in a diagnostic accuracy study – a simulation study

BMC Medical Research Methodology
Background As there are no recommendations on handling missing values in a dichotomous index test of a diagnostic study, researchers often ignore missing values in the analysis or use simple methods.
