Sample size estimation for alternating logistic regressions analysis of multilevel randomized community trials of under-age drinking [0.03%]
多级社区试验中交替逻辑回归分析的样本量估计——以防止未成年人饮酒为例

Under-age drinking is an enormous public health issue in the USA. Evidence that community level structures may impact on under-age drinking has led to a proliferation of efforts to change the environment surrounding the use of alcohol. Alth...
Assessing the measurement error properties of interviewer observations of neighbourhood characteristics [0.03%]

Interviewer observations made during the process of data collection are currently used to inform responsive design decisions, to expand the set of covariates for nonresponse adjustments, to explain participation in surveys, and to assess no...
Assessing variance components in multilevel linear models using approximate Bayes factors: A case study of ethnic disparities in birthweight [0.03%]
基于近似贝叶斯因子的多水平线性模型方差分量估计及异质性出生体重研究

Benjamin R Saville
Racial/ethnic disparities in birthweight are a large source of differential morbidity and mortality worldwide and have remained largely unexplained in epidemiologic models. We assess the impact of maternal ancestry and census tract residenc...
The risky reliance on small surrogate endpoint studies when planning a large prevention trial [0.03%]
在计划大型预防试验时对小替代终点研究的冒险依赖性

The definitive evaluation of treatment to prevent a chronic disease with low incidence in middle age, such as cancer or cardiovascular disease, requires a trial with a large sample size of perhaps 20,000 or more. To help decide whether to i...
A Spatial Poisson Hurdle Model for Exploring Geographic Variation in Emergency Department Visits [0.03%]
探索急诊就诊地理差异的Spatial Poisson Hurdle模型

Brian Neelon
We develop a spatial Poisson hurdle model to explore geographic variation in emergency department (ED) visits while accounting for zero inflation. The model consists of two components: a Bernoulli component that models the probability of an...

Comparing self-assessed indicators of subjective outcomes such as health, work disability, political efficacy, job satisfaction, etc. across countries or socio-economic groups is often hampered by the fact that different groups use differen...

Time dynamics are often ignored in causal modelling. Clearly, causality must operate in time and we show how this corresponds to a mechanistic, or system, understanding of causality. The established counterfactual definitions of direct and ...

We have previously described the content of a text by Woods and Russell, An Introduction to Medical Statistics, compared it with Principles of Medical Statistics by Hill and set both volumes against the background of vital statistics up unt...
Making predictions from complex longitudinal data, with application to planning monitoring intervals in a national screening programme [0.03%]
基于复杂纵向数据进行预测及其在国家筛查项目监测间隔期规划中的应用
M J Sweeting,S G Thompson
M J Sweeting
When biological or physiological variables change over time, we are often interested in making predictions either of future measurements or of the time taken to reach some threshold value. On the basis of longitudinal data for multiple indi...

The paper develops and applies an expert-based stochastic population forecasting method, which can also be used to obtain a probabilistic version of scenario-based official forecasts. The full probability distribution of population forecast...
