On this R-data statistics page, you will find information about the foodstamp data set which pertains to Food Stamp Program Participation. The foodstamp data set is found in the robustbase R package. You can load the foodstamp data set in R by issuing the following command at the console data("foodstamp"). This will load the data into a variable called foodstamp. If R says the foodstamp data set is not found, you can try installing the package by issuing this command install.packages("robustbase") 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 foodstamp R data set. The size of this file is about 1,578 bytes. ## Food Stamp Program Participation## DescriptionThis data consists of 150 randomly selected persons from a survey with information on over 2000 elderly US citizens, where the response, indicates participation in the U.S. Food Stamp Program. ## Usagedata(foodstamp) ## FormatA data frame with 150 observations on the following 4 variables. `participation` -
participation in U.S. Food Stamp Program; yes = 1, no = 0 `tenancy` -
tenancy, indicating home ownership; yes = 1, no = 0 `suppl.income` -
supplemental income, indicating whether some form of supplemental security income is received; yes = 1, no = 0 `income` -
monthly income (in US dollars)
## SourceData description and first analysis: Stefanski et al.(1986) who indicate Rizek(1978) as original source of the larger study. Electronic version from CRAN package catdata. ## ReferencesRizek, R. L. (1978) The 1977-78 Nationwide Food Consumption Survey. Stefanski, L. A., Carroll, R. J. and Ruppert, D.
