On this R-data statistics page, you will find information about the nassCDS data set which pertains to Airbag and other influences on accident fatalities. The nassCDS data set is found in the DAAG R package. You can load the nassCDS data set in R by issuing the following command at the console data("nassCDS"). This will load the data into a variable called nassCDS. If R says the nassCDS data set is not found, you can try installing the package by issuing this command install.packages("DAAG") and then attempt to reload the data. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the nassCDS R data set. The size of this file is about 2,641,150 bytes. Airbag and other influences on accident fatalitiesDescriptionUS data, for 1997-2002, from police-reported car crashes in which there is a harmful event (people or property), and from which at least one vehicle was towed. Data are restricted to front-seat occupants, include only a subset of the variables recorded, and are restricted in other ways also. UsagenassCDS FormatA data frame with 26217 observations on the following 15 variables.
DetailsData collection used a multi-stage probabilistic sampling scheme. The observation weight, called national inflation factor ( Sourcehttp://www.stat.colostate.edu/~meyer/airbags.htm\ ftp://ftp.nhtsa.dot.gov/nass/ See also\ http://www.maths.anu.edu.au/~johnm/datasets/airbags ReferencesMeyer, M.C. and Finney, T.
