Dear Nick,
Thank you for your response. The earlier message finally got posted. Steve has responded. All this is helpful.
However, my 8/3 questions did not again posted. I am going to talk to our IT folks and see whether they can help resolve the issue.
Regards,
Pradip

On 1) we can't help much. This email got through, so it's fine. We can't see the emails that didn't get through, so we can't examine them to spot the problem. But I've seen enough cases where people were in denial about the HTML, ejunk or attachments they were trying to send to say "Your assumption may not be correct".
You work for samhsa.hhs.gov, whatever that is, and there must be IT people who can look at your emails and tell you more.
On 2) I can't help much either. I don't know more about Cox models than you do. But Steve Samuels will likely say something. The usual guess is sorry, but that model looks complicated.

However, the addition of a 5-category factor (attained age) to the model gives me the following error message: "flat region resulting in a missing likelihood error occurred when svy executed stcox last estimates not found". Sorry I am not pasting the content from the log file, fearing that this e-mail will also bounce back.
