I hope you are all well.
I am trying to run a difference-in-difference regression analysis (if you have experience with diff-in-diff in SAS, please share any useful tips.)
So, I ran first this model to compare between the means of each categorical group:
proc glm data = daily0809;
class group tm;
model dbas = group tm group*tm/ss3;
However, I got the following Warning.
WARNING: ODS graphics with more than 5000 points have been suppressed. Use the
PLOTS(MAXPOINTS= ) option in the PROC GLM statement to change or override the cutoff.
I tried to use the plot(maxpoints=) option but I think I am not doing it properly. My data comprises 116569 observations and 8 variables.
Thanks in advance!!
