In least squares (LS) method, the unknown values of the parameters, α0, α1, α2, α3, …, αn in the regression function, f(x, α), are estimated by finding numerical values for the parameters that minimize the sum of the squared deviations between the measured responses and the functional portion of the model. Therefore, the least squares criterion is given by,
