Description: A recent software project had a requirement to derive the equation of a quadratic curve from a series of data points. That is to say, to determine a, b, and c, where y = ax2+ bx+ c. Having determined a, b, and c, I would also need a value for R-squared (the coefficient of determination).
I had a vague recollection of something called Least Squares Regression , so back to Google I went.
