Parametric and Semiparametric Model-Based Estimates of the Finite Population Mean for Two-Stage Cluster Samples with Item Nonresponse
(Blackwell Publishing Inc, 2007-12)
This article concerns item nonresponse adjustment for two-stage cluster samples. Specifically, we focus on two types of nonignorable nonresponse: nonresponse depending on covariates and underlying cluster characteristics, ...
Striatal monoamine terminals in Lewy body dementia and Alzheimer's disease
(Wiley Subscription Services, Inc., A Wiley Company, 2004-06)
We used positron emission tomography (PET) with (+)-[ 11 C]dihydrotetrabenazine ([+]-[ 11 C]DTBZ) to examine striatal monoaminergic presynaptic terminal density in 20 patients with dementia with Lewy bodies (DLB), 25 with ...
Confidence intervals with fixed proportional accuracy
(Elsevier, 1986-1987)
The problem of setting a confidence interval with fixed proportional accuracy for the mean of a normal distribution is considered. A sequential procedure is proposed; and asymptotic expansions for its average coverage ...
Singh's theorem in the lattice case
(Elsevier, 1988-12)
The asymptotic behavior of the parametric bootstrap estimator of the sampling distribution of a maximum likelihood estimator is investigated in a simple lattice case, integer valued random variables whose distributions ...

Background: Breast cancer is a major cause of morbidity, mortality, and medical expenditures among women in Canada. Essiac (Resperin™ Canada Limited, Waterloo, Ontario, Canada), a blend of at least four herbs (burdock root ...
Early events of Bacillus anthracis germination identified by time-course quantitative proteomics
(WILEY-VCH Verlag, 2006-10)
Germination of Bacillus anthracis spores involves rehydration of the spore interior and rapid degradation of several of the protective layers, including the spore coat. Here, we examine the temporal changes that occur ...
Characterization and consequences of pain variability in individuals with fibromyalgia
(Wiley Subscription Services, Inc., A Wiley Company, 2005-11)
Objective A growing body of evidence suggests that real-time electronic assessments of pain are preferable to traditional paper-and-pencil measures. We used electronic assessment data derived from a study of patients with ...
Inapparent infections and cholera dynamics
(Nature Publishing Group, 2008-08-14)
In many infectious diseases, an unknown fraction of infections produce symptoms mild enough to go unrecorded, a fact that can seriously compromise the interpretation of epidemiological records. This is true for cholera, a ...
