Residual-based Alternative Partial Least Squares for Generalized Functional Linear Models
Yue Wang, Xiao Wang, Joseph G. Ibrahim +1
Many biomedical studies collect high-dimensional medical imaging data to identify biomarkers for the detection, diagnosis, and treatment of human diseases. Consequently, it is cruc…
Fast, effective, and coherent time series modeling using the sparsity-ranked lasso
Ryan Peterson, Joseph Cavanaugh
The sparsity-ranked lasso (SRL) has been developed for model selection and estimation in the presence of interactions and polynomials. The main tenet of the SRL is that an algorith…
Ranked Sparsity: A Cogent Regularization Framework for Selecting and Estimating Feature Interactions and Polynomials
Ryan A. Peterson, Joseph E. Cavanaugh
We explore and illustrate the concept of ranked sparsity, a phenomenon that often occurs naturally in modeling applications when an expected disparity exists in the quality of info…
Measurement Error in Meta-Analysis (MEMA) -- a Bayesian framework for continuous outcome data
Harlan Campbell, Valentijn M. T. de Jong, Lauren Maxwell +3
Ideally, a meta-analysis will summarize data from several unbiased studies. Here we consider the less than ideal situation in which contributing studies may be compromised by measu…
A Calibration Approach to Transportability and Data-Fusion with Observational Data
Kevin P. Josey, Fan Yang, Debashis Ghosh +1
Two important considerations in clinical research studies are proper evaluations of internal and external validity. While randomized clinical trials can overcome several threats to…
Transporting Experimental Results with Entropy Balancing
Kevin P. Josey, Seth A. Berkowitz, Debashis Ghosh +1
We show how entropy balancing can be used for transporting experimental treatment effects from a trial population onto a target population. This method is doubly-robust in the sens…
Analysis of regression discontinuity designs using censored data
Youngjoo Cho, Chen Hu, Debashis Ghosh
In medical settings, treatment assignment may be determined by a clinically important covariate that predicts patients' risk of event. There is a class of methods from the social s…
A Framework for Covariate Balance using Bregman Distances
Kevin P. Josey, Elizabeth Juarez-Colunga, Fan Yang +1
A common goal in observational research is to estimate marginal causal effects in the presence of confounding variables. One solution to this problem is to use the covariate distri…
Predictive Directions for Individualized Treatment Selection in Clinical Trials
Debashis Ghosh, Youngjoo Cho
In many clinical trials, individuals in different subgroups have experience differential treatment effects. This leads to individualized differences in treatment benefit. In this a…
Reducing decision errors in the paired comparison of the diagnostic accuracy of screening tests with Gaussian outcomes
Brandy M. Ringham, Todd A. Alonzo, John T. Brinton +4
Scientists often use a paired comparison of the areas under the receiver operating characteristic curves to decide which continuous cancer screening test has the best diagnostic ac…
