Hello to all!
I am new to this Forum, please apologies if I am not using it right.
I have a question, does STATA allow for converting yearly data to quarterly data?
Most of my database is per year but the most important variables in my analysis are the result of auctions which can happen 2-4 times a year, so converting all the dataset to a quarterly timeline sounded good to me.
However I don't consider worthy the time of manually converting all the variables to quarterly because they are a lot.

Another option could be adding more than one event (in one variable) to one year observation.

I will copy a part of my data base :
YEAR
2009		 X1
40,130		 X2
308,740		 X3
2010 40,520 370,260
2011 40,900 448,170
2012 41,733 581,540
2013 42,203 613,200
2014 2014.1 42,670 566,850 229
2014 2014.2 42,670 566,850 34
2014 2014.3 42,670 566,850 67
2014 2014.4 42,670 566,850 234
2015 42,670 566,850 90
2016 43,130 633,960
2017 43,590 532,700 14
Please your help!
