Outlier flagging-evaluation: Flagging of values above or below 3 standard deviations of the preceding 7 and following 7 data points (rolling window = 15), and minimum 3 units above/below the average of the same preceding and following 7 values. This flagging is then followed by user inspection and an optional visual inspection of the dataset
