Using Time Series to Assess Data Quality in Telecommunications Data Warehouses
Renato Busatto · IQ · 2000
The growing complexity of telephone services, particularly in mobile telephony, and its impact upon billing data mean that phone call volume modelling techniques became crucial in the assessment of the accuracy of the information available in telecommunications data warehouses. Time series modelling, normally used for forecasting, provide a suitable tool for this purpose as well. Preliminary experiments show the relevance of the approach in the discovery of missing traffic data.
