Joinpoint regression model

I'm still relatively new to SAS and I am trying to conduct estimates using a Joinpoint regression model since I've read about how accurate it is in predictions. I have no idea where to begin in coding it though. Has anyone used this and has sample code to help me along?

Re: Joinpoint regression model

Is this for cancer data analysis?


If so, look into the JoinPoint software from NCI.

You can find lots of info (including example programs) on the web.

These are the keywords you need are:

Piecewise Regression Model in SAS

Here is a nice article (including SAS code):

Here is an example from the SAS documentation:
