Hi,
I have a monthly time series of the Dow Jones Industrial Index beginning
1928:10. I'd like to create a new variable that is just the month
number: 10, 11, 12, 1, 2, 3,.... How can I do this? I thought there
would be a month function in Gretl, but I don't see one. This question,
of course, extends to the year (1928, 1928, 1929, 1929,...) and quarter
if I have quarterly data.
Does this help?
<hansl>
open bjg.gdt
series year = 1949 + floor((t-1)/12)
series month = 1 + ((t-1)%12)
</hansl>
