Dear all,
I have observations every 4 weeks (4-week period data).
In the excel.csv file i format the cells for the date column as follows
dates11 identier variable
November 1, 2009 1
November 29, 2009 1
December 27, 2009 1
January 31, 2010 1
November 1, 2009 2
November 29, 2009 2
December 27, 2009 2
January 31, 2010 2
and then I use the commads:
gen edate1 = date(dates11, "MDY")
format edate1 %d
tsset identifier edate1
and I get the following stata message:
tsset identif2 edate1
panel variable: identif2 (strongly balanced)
time variable: edate1, 02nov2008 to 09oct2011, but with gaps
delta: 1 day
Is this message something alarming? why "gaps"? and why delta "1 day"
