Twenty-nine teams involving 61 analysts used the same data set to address research question: whether soccer referees are more likely give red cards dark-skin-toned players than light-skin-toned players. Analytic approaches varied widely across teams, and estimated effect sizes ranged from 0.89 2.93 ( Mdn = 1.31) in odds-ratio units. Twenty (69%) found a statistically significant positive effect, 9 (31%) did not observe relationship. Overall, 29 different analyses 21 unique combinations of...
Cerebral palsy (CP) is considered a pediatric condition despite most individuals with CP living into adulthood. Thus, there lack of evidence in adults CP, which includes paucity research examining mental health this population.To determine the risk depression and anxiety compared an age-, sex-, practice-matched reference group without using primary care data.Retrospective longitudinal cohort study set UK care. Data were analyzed Cox proportional hazards regression analyses adjusted for...
PReMiuM is a recently developed R package for Bayesian clustering using Dirichlet process mixture model. This model an alternative to regression models, non- parametrically linking response vector covariate data through cluster membership (Molitor, Papathomas, Jerrett, and Richardson 2010). The allows binary, categorical, count continuous response, as well discrete covariates. Additionally, predictions may be made the missing values covariates are handled. Several samplers label switching...
Abstract Background Picoeukaryotes represent an important, yet poorly characterized component of marine phytoplankton. The recent genome availability for two species Ostreococcus and Micromonas has led to the emergence picophytoplankton comparative genomics. Sequencing revealed many unexpected features about structure several hypotheses on biology physiology. Despite accumulation genomic data, little is known gene expression in eukaryotic picophytoplankton. Results We have conducted a...
To compare mortality rates for cardiovascular disease, cancer, and respiratory disease between adults with cerebral palsy (CP) the general population.A cohort study was conducted using data from CP in England, identified through a primary care set (the Clinical Practice Research Datalink), linked on death registrations Office National Statistics. Cause of categorized according to International Classification Diseases codes. Standardized ratios (SMRs) were calculated population, adjusted age,...
Research indicates that multiple outdoor air pollutants and adverse neighborhood conditions are spatially correlated. Yet health risks associated with concurrent exposure to pollution mixtures clustered factors remain underexplored. Statistical models assess the effects from pollutant limited, due problems of collinearity between area-level covariates, increases in covariate dimensionality. Here we identify profiles contextual within Los Angeles (LA) County. We then relate these term low...

Air pollution epidemiological studies suggest that elevated exposure to fine particulate matter (PM2.5) is associated with higher prevalence of term low birth weight (TLBW). Previous have generally assumed the exposure-response PM2.5 on TLBW be same throughout a large geographical area. Health effects related exposures, however, may not uniformly distributed spatially, creating need for explicitly investigate spatial distribution relationship between individual-level and TLBW. Here, we...
Abstract By drawing on large-scale online data we are able to construct and analyze the time-varying worldwide network of professional relationships among start-ups. The nodes this represent companies, while links model flow employees associated transfer know-how across companies. We use centrality measures assess, at an early stage, likelihood long-term positive economic performance a start-up. find that start-up has predictive power by using can provide valuable recommendations, sometimes...
We consider the question of Markov chain Monte Carlo sampling from a general stick-breaking Dirichlet process mixture model, with concentration parameter [Formula: see text]. This paper introduces Gibbs algorithm that combines slice approach Walker (Communications in Statistics - Simulation and Computation 36:45-54, 2007) retrospective Papaspiliopoulos Roberts (Biometrika 95(1):169-186, 2008). Our is implemented as efficient open source C++ software, available an R package, based on blocking...
Airborne particles are a complex mix of organic and inorganic compounds, with range physical chemical properties. Estimation how simultaneous exposure to air affects the risk adverse health response represents challenge for scientific research quality management. In this paper, we present Bayesian approach that can tackle problem within framework time series analysis.We used Dirichlet process mixture models cluster points similar multipollutant profiles, while adjusting seasonal cycles,...
Summary The paper investigates the dependences between levels of severity road traffic accidents, accounting at same time for spatial and temporal correlations. study analyses accidents data ward level in England over period 2005–2013. We include our model multivariate spatially structured unstructured effects to capture severities, within a Bayesian hierarchical formulation. also component we carry out an extensive comparison. results show important associations both downward trend is...
To compare the incidence of noncommunicable diseases between adults with and without cerebral palsy (CP).A cohort study was conducted using primary care data from Clinical Practice Research Datalink. Cox models, stratified by matched set adjusted for potential confounders, were fitted to risk any disease, cancer, cardiovascular type 2 diabetes mellitus, respiratory disease CP.The analysis included 1,705 CP 5,115 age-, sex-, general practice-matched CP. There evidence analyses that had 75%...
People with cerebral palsy (CP) may be at increased risk of musculoskeletal conditions due to various factors including malnutrition and abnormal levels skeletal loading.

In this work we present a statistical approach to distinguish and interpret the complex relationship between several predictors response variable at small area level, in presence of (i) high correlation (ii) spatial for response. Covariates which are highly correlated create collinearity problems when used standard multiple regression model. Many methods have been proposed literature address issue. A very common is an index aggregates all variables interest. For example, it well known that...
