Defining data points below curve defined by Spline Model

[Sonja]

Hi All

I am using the Spline Model to build a regression model for a price curve. 

The ultimate goal is to detected all data points below the regression curve - therefore I a looking the curve function. 

The Spline Model nicely plots the curve in the Effects plot and provides coefficients information - however I cannot find the curve function. 

How can I best define all data points below the curve? 

Many thanks for your help.

Hi @Sonja ,

what about using a Score tool to calculate the "predicted values" for all data (i.e. the training data used to build the model)?
The values calculated by the score tool represent the curve values, if "real" value is less than ""predicted", the point is below
the curve. Do you think, this could be an approach?

Best regards

Roland

Thanks Roland. This worked perfectly well.
