> Currently the knnRegress function calculates the prediction by averaging the
> outcomes from the k nearest neighbors. The robust flag wil cause the
> knnRegression function to calculate the prediction by taking the median of
> the outcomes of the k nearest neighbors. This will be useful when using
> knnRegression for anomaly detection.
