Witrynaan optional vector of weights to be used in the fitting process. If specified, weighted least squares is used with weights weights (that is, minimizing. sum (w*e^2) sum(w∗e2) ); otherwise ordinary least squares is used. an expression defining a subset of the observations to use in the fit. The default is to use all observations.
