Gerber and Green Dataset used by Imai

Description

This is the dataset used by Imai (forthcoming) to replicate and evaluate the field experiment done by Gerber and Green (2000). The accompanying example code provides a model with good balance which estimates the causal effect of get-out-the-vote telephone calls on turnout.

Details

The demo provided, entitled GerberGreenImai, estimates the causal effect of get-out-the-vote telephone calls on turnout. The balancing model achieves exact balance on all covariates except for age. And for age, balance is very good. This model estimates the causal effect of get-out-the-vote telephone calls on turnout to be not significantly different from zero.
