WebFit is typically used for fitting combinations of functions to data, including polynomials and exponentials. It provides one of the simplest ways to get a model from data. The best fit minimizes the sum of squares . WebVarianceEstimatorFunction explicitly defines the variance scale estimator that is used. For measurement errors, you want standard errors to be computed only from the weights and so the variance estimate should be the constant 1: In [8]:=. Out [8]=.
