Variable Names:
% BED = number of beds in home
% MCDAYS = annual medical in-patient days (hundreds)
% TDAYS = annual total patient days (hundreds)
% PCREV = annual total patient care revenue ($hundreds)
% NSAL = annual nursing salaries ($hundreds)
% FEXP = annual facilities expenditures ($hundreds)
% RURAL = rural (1) and non-rural (0) homes
Plots
Creating Histograms for all the 7 variables.
From Histrogram outliers can be seen easily in each of the 6 tuples. And data in highly non-uniform.
Lets see how different Nursing home attribute are related to each other using correlation matrix.
#correlation matrix
cormat<-cor(df[c("BED","MCDAYS","TDAYS","PCREV","NSAL","FEXP")])
