    Ax + b Least Squares Minimization Standard Form

    statdad - Correct. That's the right equation. It's the Minimum Squares Percent Error (MSPE) equation used in econometrics. I figured out there are a handful of algorithms/methods to minimize nonlinear equations. Variations of Newton's Method are fairly popular for this task. Thank you for...

    Ax + b Least Squares Minimization Standard Form

    All - Given a set of data {(xi, yi)| i = 1,2,...,m} and the regression equation f(x) = ax + b, I want to use the simplex method to minimize the equation Sigma [(yi - f(xi))/f(xi)]^2. However, I am stuck on how to initially organize the problem. I am not sure whether the equation, Sigma [(yi -...
