What's equation for R-Squared value given for chart trendlines?
I am using an exponential trendline in an Excel Chart and want to replicate
the R-Squared value the chart wizard gives. I know that RSQ would give me
this were I dealing with a linear trend. However, with exponential Microsoft
Help just says a "transformed regression model".
I was hoping someone could give me the equation, or even better offer a
function that calculates it.
Thanks
