How to calculate linear regression using least square method. In the least squares method the unknown parameters are estimated by minimizing the sum of the squared deviations between the data and the Examples of Linear, independent variables are called total least squares methods. The problem, then, is to п¬Ѓnd the smallest perturbations.
