Finally, we develop auction calendars and auction scene visualizations for viewing a set of many concurrent auctions. STAT-zoom adds the capability of looking at data summaries at various time scales interactively. We then introduce the concept of statistical zooming (STAT-zoom) which can scale up to be used for visualizing large amounts of auctions. We start by using profile plots that reveal aspects of an auction such as bid values, bidding intensity, and bidder strategies. In this article we introduce graphical methods for visualizing online auction data in ways that are informative and relevant to the types of research questions that are of interest. This is quite surprising, given that the sheer amount of data that can be found on sites such as is overwhelming and can often not be displayed informatively using standard statistical graphics. However, there is a clear void in this growing body of literature in developing appropriate visualization tools. ML has many subfields and applications, including statistical learning methods, neural networks, instance-based learning, genetic algorithms, data mining. The existing literature on online auctions focuses on tools like summary statistics and more formal statistical methods such as regression models. These research efforts are often based on analyzing data from Web sites such as which provide public information about sequences of bids in closed auctions, typically in the form of tables on HTML pages. Online auctions have been the subject of many empirical research efforts in the fields of economics and information systems. ![]()
