Curve fitting using unconstrained linear least squares methods This online calculator builds a regression model to fit a curve using the linear least squares method. If additional constraints on the approximating function are entered, the calculator uses Lagrange multipliers to find the solutions. The calculator below uses the linear least squares method for curve fitting, […]
