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

Hello,

 

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

These are the keywords you need are:

Piecewise Regression Model in SAS

OR

Segmented regression model in SAS

OR

Change point regression model in SAS

 

Here is a nice article (including SAS code):

http://people.stat.sfu.ca/~cschwarz/Stat-650/Notes/PDFbigbook-SAS/SAS-part018.pdf

Regression - hockey sticks, broken sticks, piecewise, change points

 

Here is an example from the SAS documentation:

SAS/STAT(R) 14.1 User's Guide

Example 81.1: Segmented Model

Re: Joinpoint regression model

Is this for cancer data analysis?

 

If so, look into the JoinPoint software from NCI.
