Redefining Populations of Inference for Generalizations from Small Studies
Wendy Chan, Jimin Oh, Katherine J. Wilson
With the growth in experimental studies in education, policymakers and practitioners are interested in understanding not only what works, but for whom an intervention works. This i…
The Role of Distributional Overlap on the Precision Gain of Bounds for Generalization
Wendy Chan
Over the past ten years, propensity score methods have made an important contribution to improving generalizations from studies that do not select samples randomly from a populatio…
An Evaluation of Bounding Approaches for Generalization
Wendy Chan
Statisticians have recently developed propensity score methods to improve generalizations from randomized experiments that do not employ random sampling. However, these methods typ…
Partial Identification of Treatment Effects for Generalizability
Wendy Chan
Recent methods to improve generalizations from nonrandom samples typically invoke assumptions such as the strong ignorability of sample selection that are often controversial in pr…
