In above example 'pred' is a DataFrame with column 'ID' which provides the
row ID.

Hi Shirish,
Thanks for your clarification.
Not sure how exactly I can modify the GLM-predict.dml to get some
prediction to start with. Ideally I would like the probability threshold to
be parameterized.
If I check the script at line 135-136 I can see the code which returns
means and vars -

Hi Sourav,
Yes, GLM-predict.dml gives out only the probabilities. You can put a
threshold on the resulting probabilities to get the actual class labels --
for example, prob > 0.5 is positive and <=0.5 as negative.
The exact value of threshold typically depends on the data and the
application. Dif
