Paolo Buono, Catherine Plaisant, Adalberto Simeone, Aleks Aris, Galit Shmueli, Wolfgang Jank
2007 Information Visualisation  
Time-series forecasting has a large number of applications. Users with a partial time series for auctions, new stock offerings, or industrial processes desire estimates of the future behavior.  ...  A forecasting preview interface allows users to interactively explore alternative pattern matching parameters and see multiple forecasts simultaneously.  ...  Acknowledgements: We thank the Center for Electronic Markets and Enterprises and the R.H. Smith School of Business at the University of Maryland for providing support for this project.  ...
