Cannot draw graphs. Can you give some examples on how to draw graphs?

Hi,

I have no problem running the numbers. But when I added graph to my code, suddenly the third variable does not exist.

sdid occupancy_rate record_id gap type, vce(placebo) seed(1234) graph ----+--- 1 ---+--- 2 ---+--- 3 ---+--- 4 ---+--- 5 .................................................. 50

Synthetic Difference-in-Differences Estimator

---

occupancy_rate | ATT Std. Err. t P>|t| [95% Conf. Interval] -------------+--------------------------------------------------

treatment | -0.06058 0.00648 -9.34 0.000 -0.07329 -0.04787

95% CIs and p-values are based on Large-Sample approximations. Refer to Arkhangelsky et al., (2020) for theoretical derivations. variable gap not found r(111);

My data is here: test.csv

I wonder what is wrong here and can you give some examples on how to draw the graphs?

Thank you!

Update: My time period (the gap variable) was originally from -6 to 6.

When I use sdid occupancy_rate record_id gap type, vce(placebo) seed(1234) graph

It shows the error variable gap not found r(111);

But when I do gen year = gap + 1980

Then sdid occupancy_rate record_id gap type, vce(placebo) seed(1234) graph gives me the graph.

Don't understand why though.....

hello @TXU0429 , we have a small bug with the graph option. At the moment you need the time variable named "year" for the graph output. ren gap year is an option to resolve the error.
