Hi,
I am using the Method Comparison Add-in by Russ Wolfinger to fit a Passing-Bablok regression. The add-in works great because it also adds CI's for the regression estimates. It also computes an additional orthogonal fit for comparison.
Now I am trying to calculate the predicted value at a given X point, with Confidence Intervals using the PB fit. Is there a way to do this?
Thanks!
Dave
