Gerber and Green Dataset used by Imai
Description
This is the dataset used by Imai (2005) to replicate and evaluate the field experiment done by Gerber and Green (2000). The accompanying demo replicates Imai's propensity score model which is then used to estimate the causal effect of get-out-the-vote telephone calls on turnout.

propensity score model to estimate the causal effect of
get-out-the-vote telephone calls on turnout. The propensity score
model fails to balance age.
