plot.PanelEstimate: Plot point estimates and standard errors from a PanelEstimate...

In PanelMatch: Matching Methods for Causal Inference with Time-Series Cross-Sectional Data

Plot point estimates and standard errors from a PanelEstimate calculation.

Description

The plot.PanelEstimate method takes an object returned by the PanelEstimate function and plots the calculated point estimates and standard errors over the specified lead time period. The only mandatory argument is an object of the PanelEstimate class.

Usage

## S3 method for class 'PanelEstimate'
plot(
  x,
  ylab = "Estimated Effect of Treatment",
  xlab = "Time",
  main = "Estimated Effects of Treatment Over Time",
  ylim = NULL,
  pch = NULL,
  cex = NULL,
  bias.corrected = FALSE,
  ...
)

Arguments

x	a PanelEstimate object
ylab	default is "Estimated Effect of Treatment." This is the same argument as the standard argument for plot()
xlab	default is "Time". This is the same argument as the standard argument for plot()
main	default is "Estimated Effects of Treatment Over Time". This is the same argument as the standard argument for plot
ylim	default is NULL. This is the same argument as the standard argument for plot()
pch	default is NULL. This is the same argument as the standard argument for plot()
cex	default is NULL. This is the same argument as the standard argument for plot()
bias.corrected	logical indicating whether or not bias corrected estimates should be plotted Default is FALSE. This argument only applies for standard errors calculated with the bootstrap.
...	Additional optional arguments to be passed to plot().

Examples

dem.sub <- dem[dem[, "wbcode2"] <= 100, ]
# create subset of data for simplicity
PM.results <- PanelMatch(lag = 4, time.id = "year", unit.id = "wbcode2", 
                         treatment = "dem", refinement.method = "mahalanobis", 
                         data = dem.sub, match.missing = TRUE, 
                         covs.formula = ~ tradewb,
                         size.match = 5, qoi = "att",
                         outcome.var = "y", lead = 0:4, forbid.treatment.reversal = FALSE)
PE.results <- PanelEstimate(sets = PM.results, data = dem.sub, se.method = "unconditional")
plot(PE.results)
