Return the logarithm stats for a line of best fit
Hi,
I wish to return the logarithm stats based on the log line of best fit. I can do this for linear and poly entered as an array formula as follows; For linear =LINEST(C58:C69,B58:B69,,1) For 2nd order poly (quadratic) =LINEST(C58:C69,B58:B69^{1,2},,1) How do i modify this for a logarithm? Bruce |

I should add that there is a typo in the log equation on that page.
The Equation: y = (c * LN(x)) - b Should be y = (c * LN(x)) + b The rest are a tremendous reference to keep handy. Regards Martin "MartinW" wrote in message ...
