Ok, thanks Wendy, that actually makes sense, I think.  In other words, it's not changing the equation of the predictive line...just the point at which the model chooses to assign a 1 or a 0 to the observation, correct?  I think I just expected to see a separate row in the fit statistics, but I suppose that could be considered redundant.  Appreciate the reply! ...

Hi Anna,   This is helpful in understanding the cutoff node, but I'm wondering if you can explain how to compare the results of a model that uses the cutoff to a model that doesn't.  I can't seem to get my model to show the differences.  I'm new to SAS and am not sure if I've connected the nodes correctly.  In this example, I want to compare the results of Regressions 1, 2 and 4 (which use the default cutoff of 0.5) to Regression 3 (which uses the 0.03 cutoff), but my results for Regression 3 in the Model Comparison node look the same as before I used the cutoff.   PS:  My model uses a 65% training and 35% testing dataset.   Thanks!   ...

PS:  I forgot to mention I have a 65% training and a 35% testing set (from the "Data Partition") node. ... View more

How do I use the Model Comparison node with the Cutoff node results?

Hi,   I am trying to use the Cutoff node in SAS Enterprise Miner 14.1 (university "cloud" version) for a logistic regression.  I then want to compare the results of changing the cutoff to the results I get from three other (similar) logistic regressions that don't use the cutoff, just to see the differences in model performance.   When I connect my four models (three without the Cutoff and one with) to the Model Comparison node, the results don't seem to capture the model that uses the cutoff.  It produces results, but they appear to be the same as I got before the cutoff (yes, I changed the user input cutoff value from 0.5 to 0.03).   Am I not using the Model Comparison correctly with the Cutoff node?  I'm fairly new with SAS, so I'm kinda struggling with this one and the examples I've found seem to stop short of comparing models.   Thanks in advance. ...
