Developing multicomponent interventions using fractional factorial designs
(John Wiley & Sons, Ltd., 2009-09-20)
Multicomponent interventions composed of behavioral, delivery, or implementation factors in addition to medications are becoming increasingly common in health sciences. A natural experimental approach to developing and ...
Forecasting Models of Emergency Department Crowding
(Blackwell Publishing Ltd, 2009-04)
Balanced centralized and distributed database design in a clinical research environment
(John Wiley & Sons, Ltd., 2000-06-15)
Clinical research databases can meet both research and clinical needs, but this ideal is seldom achieved. Priorities often differ for those who collect and ultimately use the data and those who develop data systems. ...
On weighting the rates in non-response weights
(John Wiley & Sons, Ltd., 2003-05-15)
A basic estimation strategy in sample surveys is to weight units inversely proportional to the probability of selection and response. Response weights in this method are usually estimated by the inverse of the sample-weighted ...
Analysis of clinical flow cytometric immunophenotyping data by clustering on statistical manifolds: Treating flow cytometry data as high-dimensional objects How to cite this article: Finn WG, Carter KM, Raich R, Stoolman LM, Hero AO. Analysis of clinical flow cytometric immunophenotyping data by clustering on statistical manifolds: Treating flow cytometry data as high-dimensional objects. Cytometry Part B 2009; 76B: 1–7.
(Wiley Subscription Services, Inc., A Wiley Company, 2009-01)
Background Clinical flow cytometry typically involves the sequential interpretation of two-dimensional histograms, usually culled from six or more cellular characteristics, following initial selection (gating) of cell ...
On summary measures analysis of the linear mixed effects model for repeated measures when data are not missing completely at random
(John Wiley & Sons, Ltd., 1999-09-15)
Subjects often drop out of longitudinal studies prematurely, yielding unbalanced data with unequal numbers of measures for each subject. A simple and convenient approach to analysis is to develop summary measures for each ...
A hot-deck multiple imputation procedure for gaps in longitudinal data on recurrent events
(John Wiley & Sons, Ltd., 2008-01-15)
We consider the analysis of longitudinal data sets that include times of recurrent events, where interest lies in variables that are functions of the number of events and the time intervals between events for each individual, ...
An experimental design for the development of adaptive treatment strategies
(John Wiley & Sons, Ltd., 2005-05-30)
In adaptive treatment strategies, the treatment level and type is repeatedly adjusted according to ongoing individual response. Since past treatment may have delayed effects, the development of these treatment strategies ...
