Hello author. I follow your vdo instruction and practice until the end. it was good but at the end to draw the line it seems something wrong or different. The total death world seems not appear. Can help check me out. I used the data as 14 Sep 2022.
Hi Ziqing, we do this to define which variables should be shown eventually in the line graph. Again, it's one way for being more lazy while making the code more flexible. :)
Seems correct. Make sure to always run the entire do file though. For local macros, you cant just execute one line, because stata "forgets" a local macro as soon as it stops executing. So in the do editor, always go ctrl+a --> ctrl+d.
great vid, but I am confused, what stops the final date truncation code from continually dropping 5 extra days each time you run it? as of course after the first time the max date is now 5 days shorter than it was. Thanks!
Excellent video! A short contribution: Instead of the 5 lines from 13 to 17, one line of command gets the job done: g newdate=date(date,"YMD")
Your videos are fantastic. They helped me a lot. Please post more.
Thanks for your videos. Hope you will post more this year!
Thanks! This finally made me understand macros!
Excellent and very helpful!
These are super helpful

Thank you for your helpful tutorials, may you please do a tutorial on how to merge multiple datasets
Yes, I think I will do something soon. This seems to be quite the hot topic. :)
Dear Sir,
May I ask why do we generate the local macro final_vars with `final_vars' `var'_world? Thank you.

What is the problem with the followin command to draw a line graph?
*5. Draw Line graph
line `final_vars' date

That's because when we run the entire do file, it always loads the full data set in the beginning, so that only 5 days are dropped in total.
dear sir, we even cant hear your voice
Yes agreed, need to pump up the volume. xD I recorded this with 0 equipment... thanks for your feedback.
@@statastic please do notify us if you do have another video with audio. already subsrice you. thank you sir
