Programming Language



eventdd estimates a panel event study corresponding to a difference-in-difference style model where a series of lag and lead coefficients and confidence intervals are estimated and plotted. These lag and lead coefficients are all relative to the passage of an event of interest, which can occur at different moments in different units of the panel. eventdd produces panel event study graphs as well as standard regression output. As well as standard inference procedures, eventdd allows for non-standard inference techniques, such as wild-bootstrapped standard errors (interacting with the user-written boottest command).
