## Context The datasets are from a [companion website](http://www.modelingonlineauctions.com/home) for the book Modeling Online Auctions, by Wolfgang Jank and Galit Shmueli (Wiley and Sons, ISBN: 978-0-470-47565-2, July 2010). ## Content The datasets contain eBay auction information on Cartier wristwatches, Palm Pilot M515 PDAs, Xbox game consoles, and Swarowski beads. **auction.csv** includes 9 variables: * **auctionid**: unique identifier of an auction * **bid**: the proxy bid placed by a bidder * **bidtime**: the time in days that the bid was placed, from the start of the auction * **bidder**: eBay username of the bidder * **bidderrate**: eBay feedback rating of the bidder * **openbid**: the opening bid set by the seller * **price**: the closing price that the item sold for (equivalent to the second highest bid + an increment) * **item**: auction item * **auction_type** **swarovski.csv** includes 5 variables: * **Seller** * **Bidder** * **Weight** * **Bidder.Volume** * **Seller.Volume** ## Acknowledgements The original dataset can be found [here](http://www.modelingonlineauctions.com/datasets). ## Inspiration Some ideas worth exploring: * For each item, what is the relationship between bids, bid time, and the closing price? Does this differ by length of the auction, opening bid, or by bidder rating?
