Sensitivity analysis for Observational studies.
Description
Observational studies are limited in that there could be
an unmeasured variable related to both the response variable
and the primary predictor. If this unmeasured variable were
included in the analysis it would change the relationship
(possibly changing the conclusions). Sensitivity analysis is a
way to see how much of a relationship needs to exist with the
unmeasured variable before the conclusions change. This
package provides tools for doing a sensitivity analysis for
regression (linear, logistic, and cox) style models.
