Current situation:
An established pattern in SAS Enterprise Miner is to use the IGN-node with binary transformation of a linear target variable to go on and make use of the scorecard node to make a logistic regression model based on the binary transformed new target variable. In Model Studio this pattern is only partly implemented as it is only the binary transformation in the IGN node that is possible to use. Due to the current limitation of Model Studio that prevents the user to switch target variable within a project, it is impossible to add a scorecard node to the IGN node as the project is initiated with a linear target variable. This behavior is confirmed in support case CS0221275.
The result is that the user has to make use of multiple Model Studio projects to be able to build a LGD model as proposed in this paper 141-2012: Building WOE Binned LGD Scorecards using SAS® Enterprise Miner™. In addition, if the user wants to build a scorecard model as a challenger model to other kinds of LGD models that make use of a linear target you end up with a scattered process with models developed here and there.
Desired outcome:
Make it possible to create a scorecard model within the same project as where the binary transformation is performed.
Added benefit:
Easier to document the model development and easier to maintain the model development project (mind you that these models and highly regulated and tend to live for years ). Easier to utilise link to Model Manager from Model Studio. When pushing a model from Model Studio to Model Manager, the default behavior is to create a new Model Manager project pr Model Studio project and this would then possibly result in multiple Model Manager projects if not resolved.
Negative effect of change:
None.
