Tim,

The infamous software is SUDAAN (SUrvey DAta ANalysis).  We have both the PC 
and mainframe versions here at CDC/NIOSH.

The LATEST version of SUDAAN is supposed to handle survival analysis (with 
complex weighting schemes).  However, we do not have that version yet as it 
JUST came out, I believe.

The weights given to observations would depend upon your sampling scheme (# 
of stages, with and without replacement, etc...).  SAS, of course, allows 
weights also, but will NOT compute the standard errors of any statistics 
correctly.  (The point estimates are fine, though.)

To obtain info' on SUDAAN, write to:

    Dr. Babu Shah
    Research Triangle Institute
    Post Office Box 12194 (3040 Cornwallis Road)
    Research Triangle Park, North Carolina   27709

I should warn you, though, SUDAAN is NOT the easiest package to 
use, or the most elegant.   Have fun!

From: Kenneth A. Hardy   KHARDY.IRSS@MHS.UNC.EDU or KENHARDY@UNCVM1.BITNET   

SUDAN is great stuff for figuring standard errors for a variety of statistical
models when the sampling scheme generating the data is complex rather than
merely simple random (i.e. stratified or cluster sampling is used). You can get
information on it from Sandra M. Paschall at the Statistical Software Center,
Research Triangle Institute, PO Box 12194, Research Triangle, NC  27709-2194.
Her number is 919-541-6602.

Hope this helps you out.

I'm guessing that you colleague was referring to SUDAAN, which is available
from Research Triangle Institute, PO Box 12194, Research Triangle Park,
North Carolina 27709. Their phone number is (919) 541-6000.
Hope this helps !

I think the name is more like SUDAAN; some extra vowels somewhere.
I think it's from Research Triangle Institute, in Research Triangle Park NC.
There are two numbers listed in the phone book for RTI; 919-541-6000 
and 919-541-6753.

Tim, I think you will get 50,000 correct answers to your question,
but let me start while I have time.  SUDAAN is at least part of
package written by B.V. (Baba, to his friends) Shah at the Research
Triangle Institute in Research Triangle Park, N.C.

If you don't get a more detailed answer by tomorrow morning from
someone, let me know, and I will get on the phone - it's a local
call from here.
P.S.:  Two A's in SUDAAN.

From: PARKERRA@ctrvax.Vanderbilt.Edu

Sudaan is sold by RTI (Research Triangle Institute) in North Carolina.
It allows for cluster sampling, but is very expensive $999 for a single
user DOS license.


From: Jim Cassell <CASSELL@UNCVM1.OIT.UNC.EDU>  or  CASSELL@UNCVM1.BITNET

SUDAAN is produced by the Research Triangle Institute in Research
Triangle Park, NC, 919-541-6000.  (They also have an 800 number, but I
don't know what it is.)  I'm not certain who the official contact person
is, but you might call the main number and ask to speak with someone
about SUDAAN.  If that fails, ask to be transferred to the main Center
for Research in Statistics number (part of RTI) and start asking them
about SUDAAN.

Several RTI employees read this list, so you may get info from them.

Best,  Jim
