    Description

      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.
