Compute simulated (sample) average treatment effects on the treated from a Zelig model estimation

ATT(object, treatment, treated = 1, num = NULL)

Arguments

object

an object of class Zelig

treatment

character string naming the variable that denotes the treatment and non-treated groups.

treated

value of treatment variable indicating treatment

num

number of simulations to run. Default is 1000.

Examples

library(dplyr) data(sanction) z.att <- zelig(num ~ target + coop + mil, model = "poisson", data = sanction) %>% ATT(treatment = "mil") %>% get_qi(qi = "ATT", xvalue = "TE")
