R Dataset / Package mediation / CEDdata

On this R-data statistics page, you will find information about the CEDdata data set which pertains to Example Data for the Crossover Encouragement Design. The CEDdata data set is found in the mediation R package. You can load the CEDdata data set in R by issuing the following command at the console data("CEDdata"). This will load the data into a variable called CEDdata. If R says the CEDdata data set is not found, you can try installing the package by issuing this command install.packages("mediation") and then attempt to reload the data with the library() command. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the CEDdata R data set. The size of this file is about 28,034 bytes.

Example Data for the Crossover Encouragement Design

Description

A randomly generated dataset containing 2000 rows and 7 columns with no missing values.

Usage

CEDdata

Format

A data frame containing the following variables, which are interpreted as results from a hypothetical randomized trial employing the crossover encouragement design.

T1:

The binary treatment indicator in the first stage.

M1:

The binary mediator variable recorded in the first stage.

Y1:

The binary outcome variable recorded in the first stage.

T2:

The binary treatment in the second stage. Equal to 1 - T1 by design.

Z:

The binary encouragement indicator for the second stage.

M2:

The binary mediator recorded in the second stage.

Y2:

The binary outcome recorded in the second stage.

Details

Note that all the observed responses are generated from an underlying distribution of potential outcomes and mediators (not shown in this dataset) satisfying the assumptions described in Imai, Tingley and Yamamoto (2012).
