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, ...
A Bayesian sensitivity model for intention-to-treat analysis on binary outcomes with dropouts
(John Wiley & Sons, Ltd., 2009-02-15)
Intention-to-treat (ITT) analysis is commonly used in randomized clinical trials. However, the use of ITT analysis presents a challenge: how to deal with subjects who drop out. Here we focus on randomized trials where the ...
An Approximate Test for Homogeneity of Correlated Correlation Coefficients
(Kluwer Academic Publishers; Springer Science+Business Media, 2003-03)
This paper develops and evaluates an approximate procedure for testing homogeneity of an arbitrary subset of correlation coefficients among variables measured on the same set of individuals. The sample may have some missing ...
A Reconfiguration of Census Tabulations: Maintaining Historical Consistency of Aggregate Industrial Categories at the County-Level
(2008-01-22)
Consistent measures are imperative for conducting valid historical analyses. Collected in the long-form survey of the decennial census, employment data has traditionally been tabulated by aggregate industrial category for ...
Providing Spatial Data for Secondary Analysis: Issues and Current Practices Relating to Confidentiality

Spatially explicit data pose a series of opportunities and challenges for
all the actors involved in providing data for long-term preservation and secondary
analysis—the data producer, the data archive, and the data user. ...
Changing Agrarian Landscapes Across America: A Comparative Perspective

Proximity to death and participation in the long-term care market
(John Wiley & Sons, Ltd., 2009-08)
The extent to which increasing longevity increases per capita demand for long-term care depends on the degree to which utilization is concentrated at the end of life. We estimate the marginal effect of proximity to death, ...
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 ...
Estimation of the proportion of overweight individuals in small areas—a robust extension of the Fay–Herriot model
(John Wiley & Sons, Ltd., 2007-06-15)
Hierarchical model such as Fay–Herriot (FH) model is often used in small area estimation. The method might perform well overall but is vulnerable to outliers. We propose a robust extension of the FH model by assuming the ...
