So in … WebI have a Java code that performs a linear regression on a set of data using the Gauss-Jordan elimination. It calculates a linear, quadratic and cubic functions using the least squares method. My problem is choosing a function out of the three that best models my data. This is ofcourse, without plotting the curve.
