ggdid.MP

either a <code>MP</code> object or <code>AGGTEobj</code> object

object

optional y limits for the plot; settng here makes the y limits
the same across different plots

ylim

xlab

ylab

title

optional gap between the labels on the x-axis. For example,
<code>xgap=3</code> indicates that the labels should show up for every third
value on the x-axis. The default is 1.

xgap

The number of columns to include in the resulting plot. The
default is 1.

ncol

Whether or not to include a legend (which will indicate color
of pre- and post-treatment estimates). Default is <code>TRUE</code>.

legend

A function to plot <code>MP</code> objects

The standard Difference-in-Differences (DID) setup involves two periods and two groups -- a treated group and untreated group. Many applications of DID methods involve more than two periods and have individuals that are treated at different points in time. This package contains tools for computing average treatment effect parameters in Difference in Differences setups with more than two periods and with variation in treatment timing using the methods developed in Callaway and Sant'Anna (2020) <https://www.ssrn.com/abstract=3148250>. The main parameters are group-time average treatment effects which are the average treatment effect for a particular group at a a particular time. These can be aggregated into a fewer number of treatment effect parameters, and the package deals with the cases where there is selective treatment timing, dynamic treatment effects, calendar time effects, or combinations of these. There are also functions for testing the Difference in Differences assumption, and plotting group-time average treatment effects.
