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.
  • PredictedResponseDelta gives a list of values which measure the effect of removing a data point on the fitted response values.
  • The ith element in the list measures the effect of removing the ith element of the data set.
  • PredictedResponseDelta is also referred to as DFFITS.
