## Randomization Inference in the Regression Discontinuity Design: An Application to Party Advantages in the U.S. Senate

### Description

This is the replication data for "Randomization Inference in the Regression
Discontinuity Design: An Application to Party Advantages in the U.S. Senate",
published in 2015 in *Journal of Causal Inference*. I use these data to
teach about regression discontinuity designs.

### Usage

```
CFT15
```

### Format

A data frame with 1390 observations on the following 9 variables.

`state`

a numeric vector for the state. This is ultimately a categorical variable.

`year`

a numeric vector for the year of the election.

`vote`

a numeric vector for the Democratic vote share in the *next* election (i.e. six years later).

`margin`

a numeric vector for the Democratic party's margin of victory in the statewide election. This is the running variable, in RDD parlance.

`class`

a numeric vector for the class to which each Senate seat belongs.

`termshouse`

a numeric vector for the Democratic candidate's cumulative number of terms previously served in the U.S. House.

`termssenate`

a numeric vector for the Democratic candidate's cumulative number of terms previously served in the U.S. Senate.

`population`

a numeric vector for the population of the Senate seat's state.

`treatment`

a numeric vector that is 1 if `margin`

> 0 and is 0 if `margin`

< 0.
