The Power of a Sensitivity Analysis and Its Limite available for analysis. In parallel, in an observational study, the power of a sensitivity analysis anticipates the outcome of a sensitivity analysis that will be performed when the observational data are available for analysis. In both cases, it is imagined that the data will be generated by a pa

Uncommon but Dramatic Responses to Treatmentague. What if most subjects are not much affected by treatment, but a small fraction, perhaps 10% or 20% of subjects, are strongly affected? On average, such an effect may be small, but not at all small for the affected fraction. Is such an effect insensitive to small and moderate unobserved biases?

Observational studies are common in most fields that study the effects of treatments on people,

The fine balance constraint and the distance can emphasize different covariates. When exact balance is unobtainable, fine balance can be used to obtain a specific pattern of imbalances.

One appendix contains a short introduction to R. A second appendix contains short R functions used to create distance matrices used in matching.
