PredictedResponseDelta
As of Version 7.0, PredictedResponseDelta has been renamed to "FitDifferences" and has become a property of LinearModelFit.
PredictedResponseDelta
is a possible value for the RegressionReport option for Regress and DesignedRegress which represents the effect on predicted values if data points are omitted.
更多信息和选项
- To use PredictedResponseDelta, you first need to load the Regression Common Functions Package. You can do this by using Needs["LinearRegression`"], which will automatically load the Regression Common Functions Package, or you can load the package directly by using Needs["RegressionCommon`"].
- PredictedResponseDelta gives a list of values which measure the effect of removing a data point on the fitted response values.
- The i
element in the list measures the effect of removing the i
element of the dataset. - PredictedResponseDelta is equivalent to StudentizedResiduals Sqrt[HatDiagonal/(1-HatDiagonal)].
- PredictedResponseDelta is also referred to as DFFITS.
