Examples

dem.sub <- dem[dem[, "wbcode2"] <= 100, ]
dem.sub.panel <- PanelData(dem.sub, "wbcode2", "year", "dem", "y")
# create subset of data for simplicity
PM.results <- PanelMatch(panel.data = dem.sub.panel,
                         lag = 4, 
                         refinement.method = "mahalanobis",
                         match.missing = TRUE,
                         covs.formula = ~ I(lag(tradewb, 1:4)) + I(lag(y, 1:4)),
                         size.match = 5, qoi = "att",
                         lead = 0:4, forbid.treatment.reversal = FALSE)
extract(PM.results, qoi = "att")
extract(PM.results) # valid since att is specified
