Retrive score in Logistic Regression (Microsoft Neural Network Viewer - SQL Server 2005)

Hi!

I bought the book "Data Mining with SQL Server 2005", but I can't find
the solution to a problem I have.

I want to retrieve from C# the logistic regression Attribute Value
(AV) Scores for the Logistic Regression Algorithm. I can see the
Scores from the Microsoft Logistic Regression Viewer (the same of
Neural Network Viewer), but I cannot retrieve them via DMX, OLEDB or
similar.

Otherwise, is there a formula that I can use to compute that score
from the coefficient, support, or probability values of the Attribute
Value pair (I can read this values from DMX)?
I can access to them via DMX:

NODE_DISTRIBUTION -> SUPPORT and PROBABILITY ATTRIBUTE_VALUE...

with a query like

SELECT FLATTENED (SELECT ATTRIBUTE_NAME, ATTRIBUTE_VALUE FROM
NODE_DISTRIBUTION WHERE VALUETYPE = ... ) FROM [MyModel].CONTENT WHERE
NODE_TYPE ....

Thanks in advance

Regards,
Marco
