Description
In certain cases with low event rate and large bucket span (e.g. `bucket_span: 1d` with a single event in the bucket), the anomaly detection model fails to recognize the linear trend. As an effect, is also forecasts a decreasing trend smoothly regressing to the mean as the prediction horizon increases.
