Getting Started with SAS Enterprise Miner 14.3, Decision Tree Results Counts are not integers.

I followed the tutorial Getting Started with Enterprise Miner 14.3 and noticed that my result from the Decision Tree node seems wrong. The Tree window from the Decision Tree node shows how the data is splitted. I noticed that the counts (please see the image below) are fractional.

In page 23 of the tutorial, Number of Observations are also not integers.

Shouldn't counts and number of observations be integers?

Thank you,

Ken

Interesting observation. It would make sense that the number-of-observations are integers. However, your results are similar to the suggested output by SAS themselves so I supposed it isn't a wrong property setting on the decision tree node.

If you run the tree in Interactive mode, the number of observations should adjust back to being integers.

I suspect that this could be due to the significant figures allocated for the output.
