Freaks,

Does anyone know a site that details how to implement a non-linear (i.e curved graph) regression algorithm - also known as a "line-of-best-fit" algorithm? My devices requires the user to input 7 points of interest along a graph (mL versus degress celcius) so the device can then calculate a value based on the closest projected value possible.

For example, a curved graph is shown (in ASCII) below, with the seven points marked as "X" 's.

| _X______________.

mL's | ____X____X/ \X

/se | ..X...''''X'''' \X

----------------------------------------------------------------

Degrees Celcius

The device should be able ot pinpoint with the best possible accuracy any value on the graph, using only the seven given data points. Any ideas?
