We use the lm function from the R statistical software to build the linear models. We have 4 covariates and we build 5 linear models, 4 univariate models with each of the covariates, and 1 including all the covariates. The results are given below:
Income, CPDU, and HHS all appear significant in the univariate models. Though Residential is significant, the R-square is very poor. The overall model is also significant model and the R-square is the highest.
