For energy star rated building, the adjusted R^2 for
2013 data is 0.978 which means the linear fit is passing through majority of
the data. Same conclusion can be made for the 2014 data with adjusted R^2
equals 0.975. For buildings with greater than 50 stars, the R is 0.980 for 2013
and 0.978 for 2014, respectively. In the appendix below both OLS plots show data
below the median and above the median energy data for two consecutive years.
