In this paper, we describe the R package mediation for conducting causal mediation analysis bio365 soil for sale in applied empirical research.In many scientific disciplines, the goal of researchers is not only estimating causal effects of a treatment but also understanding the process in which the treatment causally affects the outcome.Causal mediation analysis is frequently used to assess potential causal mechanisms.
The mediation package implements a comprehensive suite of statistical tools for conducting such an analysis.The package is organized into two distinct approaches.Using the model-based approach, researchers can estimate causal mediation effects and conduct sensitivity analysis under the standard research design.
Furthermore, the design-based approach provides several analysis tools that are applicable under different experimental designs.This approach requires weaker assumptions than the model-based approach.We also implement a statistical method for dealing with multiple (causally dependent) mediators, which are often encountered in practice.
Finally, the baseball scoreboards for sale package also offers a methodology for assessing causal mediation in the presence of treatment noncompliance, a common problem in randomized trials.
