So predicting x for given y is a statistical heressy!! I mean you can still calculate x', but don't write home about it!

My 2 cents worth!

So as long as I'm sloppy and inaccurate with my x measurements, then I'm okay?

Dave,

If there are errors in measuring x and y then one needs a different set of equations to calculate the slope and intercept--the Demming regression! :-)
