derived from the coeffiecients of a regression analysis.

And, when re-plotting data recalculated from the trendline equation for

original data, it is not the same - however when fitting a trendline to this

re-plotted data the same equation as the oringinal data is displayed!

Am I not writing the equation correctly, is this a genuine discrepency? Am

especially interested in polynomial fitted trendlines.

Many Thanks
