Hello,
For my dissertation I am using allsynth to do DiD with unemployment rates. I have both quarterly and yearly data, it is panel data. Using yearly data it works fine but with my quarterly data it has some trouble.
I use the following code:
bysort region (qdates): gen date=tq(2005q1)+_n-1
format date %tq
xtset regcode date
drop if regcode ==12
drop if regcode ==13
drop if regcode ==1
drop if regcode ==6
this is where i encournter problems. I have formatted the data as quarters but i cannot run allsynth like this:
allsynth UR UR(2014q1) UR(2011q1) UR(2005q1), trperiod(2014q1) trunit(11) figure gapfigure(placebos) pval keep(refugeeresults) plac rep
This also does not work:
allsynth UR UR('=tq(2014q1)') UR('=tq(2011q1)') UR('=tq(2005q1)'), trunit(11) trperiod('=tq(2014q1)') figure gapfigure(placebos) pval keep(refugeeresults) plac rep
The only way it works is if i use the numbers that correspond to quarters:
allsynth UR UR(216) UR(204) UR(180), trperiod(216) trunit(11) figure gapfigure(placebos) pval keep(refugeeresults) plac rep
but this means that my graphs are labelled with numbers and not quarters. Any idea how to fix this so the graphs have proper labels?
Would appreciate any help!
