On this R-data statistics page, you will find information about the Hospital data set which pertains to Hospital data. The Hospital data set is found in the vcd R package. You can load the Hospital data set in R by issuing the following command at the console data("Hospital"). This will load the data into a variable called Hospital. If R says the Hospital data set is not found, you can try installing the package by issuing this command install.packages("vcd") 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 Hospital R data set. The size of this file is about 76 bytes.

R project statistics dataset table

No	Name	Levels
1	Visit Frequency	Regular, Less than monthly, Never
2	Length of Stay	2--9 years, 10--19 years, 20+ years

Details

Wing (1962) who collected this data concludes that the longer the length of stay in hospital, the less frequent the visits.

Haberman (1974) notes that this pattern does not increase from the "Less than monthly" to the "Never" group, which are homogeneous.
