Subject: st: combining values distributed over multiple observations
Hello - this seems like an exceedingly simple question, but couldn't find a
reference to relevant syntax in the help. What I'm essentially trying to do
is go from the below format, where a given variable "A" takes different
values at discrete observations arrayed over T1-T5:
var T1 T2 T3 T4 T5
A .129 . . . .
A . .647 . . .
A . . .991 . .
A . . . .582 .
A . . . . .043
to the following format, wherein all values of A at each time are compressed
into one observation :
var T1 T2 T3 T4 T5
A .129 .647 .991 .582 .043
It seems to be at the intersection of ideas behind reshape / stack (and even
stjoin - except it's not survival-time data). Yet doesn't fall neatly within
any (or does it?)
Thanks in advance,
Mark
