Talk:Deming regression
From Wikipedia, the free encyclopedia
This is a request made after much frustration with this topic: Would someone who knows how to calculate a Deming regression please share that information? What is given in this Deming article is the standard text book explanation. Frankly, despite 25 years as a professional clinical chemist, I have yet to find anyone who can actually do the Deming regression. Can anyone help? Otherwise, discussion of something like Deming regression that nobody in real life can actually do is a futile theoretical undertaking. Is there a "spreadsheet" available to do it?
I speculate that the Deming line is the average of the slopes and intercepts of the two regression lines that one gets when one calculates regression lines for the same X vs Y data upon reversing the axes (X vs Y, then Y vs X). But then, I am not sure.
