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.
