汽车数据集(cars dataset)_数据挖掘_科研数据集(3)

This was the 1983 ASA Data Exposition dataset. The dataset was collected by Ernesto Ramos and David Donoho and dealt with automobiles. Data on mpg, cylinders, displacement, etc. (8 variables) for 406 different cars. The dataset includes the names of the cars.

fine. If you choose to illustrate some of the more sophisticated capabilities of your software and can do so without losing relevancy to the data, that is fine, too. This year, there will be no Committee commentary on the individual presentations, so you are not competing

with other presenters. The role of each presenter is to do his/her best job of presenting their statistical graphics technology to the viewers.

Each participant will be provided with a 6'(long) by 4'(tall) posterboard on which to display the results of their analyses. This is the same format as last year. You are encouraged to remain by your presentation during the Exposition to answer viewers' questions. Three

copies of your presentation must be submitted to me by July 1. Movie or slide show presentations cannot be accommodated (sorry). The Committee will prepare its own poster presentation which will orient the viewers to the data and the purposes of the Exposition.

The ASA has asked us to remind all participants that the Exposition is intended for educational and scientific purposes and is not a marketing activity. Even though last year's participants did an excellent job of maintaining that distinction, a cautionary note at this point is appropriate.

Those of us who were involved with the 1982 Exposition found it worthwhile and fun to do. We would very much like to have you participate this year. For planning purposes, please RSVP (to me, in writing please) by April 15 as to whether you plan to accept the Committee's invitation.

If you have any questions about the Exposition, please call me on

(301/763-5350). If you have specific questions about the data, or the analysis, please call Karen Kafadar on (301/921-3651). If you cannot participate but know of another person or group in your organization who can, please pass this invitation along to them.

Sincerely,
