The effects on survival of early treatment of human immunodeficiency virus infection.
(New England Journal of Medicine, 1992-04-16)
BACKGROUND. Zidovudine has been shown to prolong survival in patients with the acquired immunodeficiency syndrome (AIDS) and, in persons with human immunodeficiency virus (HIV) infection but not AIDS, to delay the progression ...
FINE PARTICULATE AIR POLLUTION AND MORTALITY IN 20 U.S. CITIES, 1987â 1994
(New England Journal of Medicine, 2000-12-14)
BACKGROUND: Air pollution in cities has been linked to increased rates of mortality and morbidity in developed and developing countries. Although these findings have helped lead to a tightening of air-quality standards, ...
Relationship of somatosensory evoked potentials and cerebral oxygen consumption during hypoxic hypoxia in dogs
(American Heart Association, 1986)
The effects of hypoxic hypoxia on cerebral hemodynamics and somatosensory evoked potential (SEP) were studied in 10 pentobarbital anestheteized dogs. Cerebral blood flow (CBF) was measured using the venous outflow technique ...
Marginalized Multilevel Models and Likelihood Inference
(Institute of Mathematical Statistics, 2000)
Hierarchical or "multilevel" regression models typically parameterize the mean response conditional on unobserved latent variables or "random" effects and then make simple assumptions regarding their distribution. The ...
Feedback Models for Discrete and Continuous Time Series
(Statistica Sinica, 1991)
In public health research, it is common to follow a cohort of subjects over time, observing a vector of health indicators and a set of covariates at each of many visits. An objective of analysis is to characterize the ...
Spatial and Temporal Variation in PM2.5 Chemical Composition in the United States for Health Effects Studies
(Environmental Health Perspectives, 2007-07)
Inference Based on Estimating Functions in the Presence of Nuisance Parameters
(Institute of Mathematical Statistics, 1995)
In many studies, the scientific objective can be formulated in terms of a statistical model indexed by parameters, only some of which are of scientific interest. The other "nuisance parameters" are required to complete the ...
