SQL Server Excel Add In for Data Mining: How do I retrieve the coefficients underlying the logististic regression model in excel

Question

I constructed a logistics regression model inside Excel using the Data Mining Add In.  I would like to see the coefficients for each input variable.  I can't seem to find this inside excel.  I tried running queries in DMX inside
Mgt Studio but that seems to return multiple coefficients
for each input  variable.  I am seeking
ONE coefficient for each variable.
Other applications I have used in the past provided the intercept and one coefficient for each input variable.  Can someone advise on how I can achieve that inside excel or Analysis Services?
Thanks
Rich

We have this problem when we install the add-in using an Administrator's login ID.
The problem is that the add-in automatically registers the Excel add-in. This causes a whole host of problems, including the one you describe (even when we install with the user as the admin on their own machine). Other problems include conflicts with other Add-ins (e.g. nVision) & utlities that import PDF into Excel.
For our Citrix environment we do the following:
· Install Essbase Add-In as Administrator
· Replace “ntuser.dat” file in Default User profile with the “ntuser.dat” file from Administrator’s profile. (Replace C:\Documents and Settings\Default User\NTUSER.DAT with C:\Documents and Settings\Administrator\NTUSER.DAT).
· Delete existing user profile from the system
Once user logs back in, a new profile will be created to work with Essbase add-in.
Note:
1. 1. NTUSER.DAT file is a hidden file. It is only visible if show hidden file option is enabled
2. Deleting user profile from the system remove all user customization such as shortcuts, favorites, pst file etc. as well.
BUG NOTE: When you try to Unregister the Excel Add-in from your Start button, the shortcut points to the wrong file name. The file name should be "unRegExcelAddin.exe"
I hope this helps.
