Jeph,
Based on your table, it looks like ties are included in determining the next
value in the ranking. You have 5 observations tied with a rank of 1, so the
next ranking that appears is 6, and so on.
Best,
Melony

Subject: st: rank error?
Hi all,
According to the documentation, egen's -rank- function should,
with -field- or -track- switches, give me consecutive ranks. Yet
when I try:
. egen rank=rank(var1), track
I get non-consecutive ranks:
. tab rank
track rank |
of (beta1) | Freq. Percent Cum.
------------+-----------------------------------
1 | 5 0.83 0.83
6 | 5 0.83 1.66
11 | 6 1.00 2.66
17 | 8 1.33 3.99
25 | 8 1.33 5.32
33 | 4 0.67 5.99
.
.
.
I've been looking at this for half an hour and finally figured
either there's something wrong with egen's rank, or there's something
wrong with me.
Any opinions?
cheers,
Jeph
