Clicking on the Help button brings up the example tabular x and y data that I used. The help page also has the correct coefficients for linear, logarithmic and power regression. Also I think the cell with the label "LN(X1)" is mislabeled. In the same help page it states that: "Power regression: Find a power curve in the form of y = a.x^b, where a is the coefficient, b is the power that best fits the data." So there shouldn't be any logarithmic operation performed on X. And further, after a power regression has been performed, the result for "LN(X1)" is in fact b or the intercept. The result for "Intercept" on other hand is a mystery. I don't know how it fits into the equation y = a.x^b (In reply to m.a.riosv from <a href="show_bug.cgi?id=142643#c2">comment #2</a>) > Please can you attach the example file?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
