I am trying to create an index for each individual in an
unbalanced panel. The index should take the value 0 for the
first time series observation for the individual and 1 for
all other values.
My problem is that I can't find the right syntax to replace
the index with 0 if this is the first time series
observation. How do I refer to the smallest observation in a
conditional statement?
gen s = 1
bysort indiv: rep s = 0 if year == smallest(year)?
Thanks.
