- Comment/Request
- The Log Regression showed much better correlation to my data than the "built-in" used in excel chart curve-fit utility.
I am told there''s a better way to fit this particular data by using a "sum of log regressions", where 2 independent correlated variables that both follow log function can be modeled. I wold appreciate any feedback, but I''m afraid the details are unknown to me.
