checking site's analysis vs LibreCalc. Had 1000 data pairs, very useful to show that despite a seemingly very high fit correlation, as one fits subsets toward the higher end, one quickly realizes that rather than 1.0x^2+3x (this site found ~1.0x^2+x ), the true fit is tending toward x^2.

Quadratic Regression Calculator. This Quadratic Regression Calculator quickly and simply calculates the equation of the quadratic regression function and the associated correlation coefficient. In addition, it generates a scatter plot that depicts the curve of best fit. You can use the quadratic regression calculator in three simple steps:

To approximate a Sine curve with a quardric equation to generate a signal for a computer music system. Also to see if you can use this to calculate sine values using two quadratic equations with one of them being the correction value add to the other to get it. ... It would be nice to be able to fit the curve, specifically through the origin.
