How to hold or display y-values of a nonlinear (specifically ridge) regression in Spotfire.

[Grant Baker]

I have a visualization that uses a ridge regression and I would like to call to the y-values of the ridge regression line in a calculated column so that I can calculate residuals. Is there any way that I can output the y-values of the regression line

I know that if I had a linear regression I could just use the given equation and then plug in the x-values, but my regression is based on column values so it does not give the option to show an expression.

Thanks in advance.
