Hi Linlin,
My breakfast usually caries me through the day. I just eat a snack around 13h30. Sometime I bring a fruit but when I can, I go out and get some sushi or granola bars or (guilt) a bag of chips. I haven't looked for books yet. But I will. It's nice and sunny here, about 1C. I'll go out later.

Enjoying your time outside! The book Fortress Besieged is my most favorite book. You can find every character in today's society. There is Chinese version of the book in the local library. I am going to read the English traslation to see how close it is to the Chinese one.

How is Canada's Gun control law? There is another horrible event in the US.

I just ordered Fortress Besieged from the municipal library. There was only one copy available in another branch. It is a dual Chinese/English edition. I should get it next week, normally.

This algorithm made it possible to estimate incidense rates in large register-based studies with a cohort size of several million individuals. Although this was also possible with Poisson regression, it can be done more elegantly with Cox regression as it allows for better adjustment for the underlying time as well as stratifying variables.  I agree it would be helpful to have the algoritm implemented in phreg, as it seems more trustworthy to cite an official SAS product rather than a user-made macro.

The suggested method is now implementedSmiley Happy

In SAS/STAT 14.1 (and later versions I guess), the faster method can be appled by writing "FAST" as an option.

PROC PHREG data=mydata FAST;
