     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.

_D_e_t_a_i_l_s:

     The demo provided, entitled 'GerberGreenImai', uses Imai's
     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.
