Similarity-Based Forecasting with Simultaneous Previews: A River Plot Interface for Time Series Forecasting
2007
Information Visualisation
Preserved Fulltext
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. ...
