Classical event study plot — EventStudyPlot_Classical • fdid

This EventStudyPlot_Classical function is to draw the classical event study plot with point-wise confidence intervals for event study coefficients.

Usage

EventStudyPlot_Classical(object, pos.legend = "top", scale.legend = 1, ...)

Arguments

object: an object of class "fdid_scb". The object to be plotted.
pos.legend: a character value of "top" or "bottom" that indicates the position of legend. If NULL, the legend is not printed.
scale.legend: a positive number that defines the size of legend. If pos.legend is NULL, the value of scale.legend is ignored.
...: Additional arguments to be passed to EventStudyPlot_Classical.

Value

The EventStudyPlot_Classical function returns a classical event study plot with point-wise confidence intervals for event study coefficients.
