Hi All,
The big green guy here, just wanted to let you all know that we now have the reputation system in place, the reputation system allows you to give a visible pat on the back to those that have helped you or whose information has been helpful.

You will see an icon in every post (Light Blue scales), click this to give the reputation point to whom you think deserves it, a green square appears for a reputation with more and more adding over time.Pretty soon you will see a string of green squares appear in the top right of your posts as your reputation grows and your forum presence!

Good Luck!
The Hulkster!

"circunferential regresion"
Dear all, I need help with the following issue .
I have several (about 1000) points (x,y) that IŽd like to aproximate with a circunference.
The idea is to find the center (x0,y0) and the R for which the sum of the squares of the distances from the given points to the closest point of the circunference is minimum.

Is there any formula I could use?
If not, any idea about how to proceed?

Thanks!

Without actually seeing the data, it's hard to think of a ready built-in function that will do it. I expect Solver would tackle this problem pretty easily once you get the spreadsheet set up.
