In regression models fitted to data from complex survey designs, sampling weights often incorporate non-essential variation, inflating variance estimates. Stabilized weights mitiga…
Choosing good subsamples for regression modelling
Thomas Lumley, Tong Chen
A common problem in health research is that we have a large database with many variables measured on a large number of individuals. We are interested in measuring additional variab…
Analysis of Error-prone Electronic Health Records with Multi-wave Validation Sampling: Association of Maternal Weight Gain during Pregnancy with Childhood Outcomes
Bryan E. Shepherd, Kyunghee Han, Tong Chen +6
