Seasonal Hybrid ESD algorithm

You've identified a repeating seasonal cycle in the nitrate data, with a period of 12 months. You are now ready to apply the Seasonal-Hybrid ESD algorithm to find out if there are anomalies present in the data.

Instructions

100 XP

Use the AnomalyDetectionVec function to run the Hybrid-ESD algorithm over the nitrate concentrations.
You will need to specify the input arguments:
x: a vector of values
period the period of any repeating pattern
