Weights

Weights
is an option for Regress and NonlinearRegress which specifies weights for the input data.

To use Weights, you first need to load the Regression Common Functions Package. You can do this by using Needs["LinearRegression`"] or Needs["NonlinearRegression`"], which will automatically load the Regression Common Functions Package, or you can load the package directly by using Needs["RegressionCommon`"].

Possible settings for Weights are Automatic, a list of numbers with the same length as the data, or a pure function.

With the default setting Weights->Automatic, each data point is given a weight of 1.
