Changing IVs in Logistic Model

​Hi, I'll try to be succinct: I created a logistic regression model, and based on the output, wanted to remove an IV from the model spec and rerun. When I go in to Modify, and remove the variable, I get the error message that "All DV values are excluded", and the model stops running. What is happening? Why can't I just remove a variable and rerun the model? Thanks for any help I can get.

    Hi David, 

    This is a product issue that was fixed in the 10.7.3 update, released on 24-Oct-2018.
    We recommend upgrading to the latest version of Knowledge Studio (10.9 as of today).
    Please download version 10.9 from https://downloads.angoss.com/ 

    Note:
    - 10.9 can be installed side by side with 10.7 (no need to uninstall 10.7 if you want to keep it for some time just in case)
    - 10.9 is compatible with projects created in v 10.7 and older 10.x versions. It will also use your current license, but after installing 10.9 you need to just re-install it from our license portal.

    I have sent you detailed instructions in my update to the Support Case that you opened.

    Best regards,
