Feed: AnalyzeCore by Sergey Bryl' – data is beautiful, data is a story. The larger and more complex the business the more metrics and dimensions. One day you understand that it is impossible to track them with only your eyes. Reducing the number of metrics and/or dimensions can prevent us from tracking all aspects of the business or analyzing aggregated data (for example, without dimensions), which can substantially smooth out or hide the anomalies. In such a situation, the detection of any anomalies after the actual occurrence can either be missed or have a significant time gap. Therefore, we have ... Read More
