The HOSPCOST2.DATA file contains 51 cases of average cost per day (in $) and average total cost per stay in each of the 50 states + D.C. (3 variables). From US Statistical Abstracts, 1985 - abstracted by Dan Zelterman. CASES, VARIABLES AND INPUT 51 cases and 3 variables. A simple example where the unit of observation is not a person but an aggregate. Data may be input by simply listing the variables. ANALYSES Simple linear regression with scatter and residual plots. A computation in the data step will yield a new variable: 'length of stay' which can then also be used in regression. Grouping of the states by geographic regions may be of interest for ANOVA. Can also illustrate map/graphics using SAS/GRAPH or S+ capabilities.
