add_reps function

add_reps

This function will run additional simulations of the unobserved confounder and add the results to the object returned from the previous call to OVtool::ov_sim

add_reps(OVtool_results, model_results, more_reps)

Arguments

• OVtool_results: The object returned from OVtool::ov_sim()
• model_results: The object returned from OVtool::outcome_model()
• more_reps: The number of additional repetitions the user wants to simulate the unobserved confounder

Returns

add_reps returns an updated object returned from OVtool::ov_sim()

Examples

data(sud)
sud = data.frame(sud[sample(1:nrow(sud),100),])
sud$treat = ifelse(sud$treat == "A", 1, 0)
sud$wts = sample(seq(1, 10, by=.01), size=nrow(sud), replace = TRUE)
outcome_mod = outcome_model(data = sud,
                            weights = "wts",
                            treatment = "treat",
