In synth-inference/synthdid: Synthetic Difference-in-Difference Estimation

Plots unit by unit difference-in-differences. Dot size indicates the weights omega_i used in the average that yields our treatment effect estimate. This estimate and endpoints of a 95% CI are plotted as horizontal lines. Requires ggplot2

Description

Plots unit by unit difference-in-differences. Dot size indicates the weights omega_i used in the average that yields our treatment effect estimate. This estimate and endpoints of a 95% CI are plotted as horizontal lines. Requires ggplot2

Usage

synthdid_units_plot(
  estimates,
  negligible.threshold = 0.001,
  negligible.alpha = 0.3,
  se.method = "jackknife",
  units = NULL
)

Arguments

estimates	as output by synthdid_estimate. Can be a single one or a list of them.
negligible.threshold	Unit weight threshold below which units are plotted as small, transparent xs instead of circles. Defaults to .001.
negligible.alpha	Determines transparency of those xs.
se.method	the method used to calculate standard errors for the CI. See vcov.synthdid_estimate. Defaults to 'jackknife' for speed. If 'none', don't plot a CI.
units	a list of control units — elements of rownames(Y) — to plot differences for. Defaults to NULL, meaning all of them.
