an error message in survival node using SAS E Miner

Posted 01-16-2018 10:46 AM (717 views)

I used survival node to develop a model, but I got an error message, "All events appear to have occurred in the first time interval. Please check your data or properties." I checked my data and I am sure that not all events appear to have occurred in the first time interval....What has happened? Thank you!

Oh, I have solved the problem. The time ID variables got reversed, that is, start_date has been set as end date, and end date has been set as start date. It is odd. I have changed it and now it is working.
