To Statalist
I have panel data of 2000 tickers, excess returns (r) and various
fundamental variables such as earnings yield (ep), momentum(mom),
earnings revision (rev), over a 120 month period. I am trying to use
the var command to develop a time series forecast for each individual
stock's excess return. I realize that I have to analyze one ticker
(stock) at a time with the time series approach and assumed that using
the foreach command would work.
tsset
panel variable: xticker (unbalanced)
time variable: date, 2000m2 to 2009m6, but with gaps
delta: 1 month
foreach xticker in dcm.dfa1.dat{
2. tsset date
3. var r ep mom rev
4. }
repeated time values in sample
r(451);
However, I get the repeated time values in sample r(451).
Any assistance is appreciated.
Thank you,
