HedonicTwo

This is to improve the two residential hedonic models: rsh and rrh. We want to bring in one or two logsum-based measures to represent accessibility. The new measures to test are mwt15 and nwt15. It is probably best to remove a number of variables and then try a model with only mwt15 or both nwt15. The variables to remove are: bart1, bart2, bart3a, lrt1, embarcadero, jobs_45, and stanford. With that simpler mode, mwt15 should be positive. Ideally, nwt15 would also be positive (but it they two are fairly correlated so it may not work). The try re-entering some of the variables taken out: bart1 and bart2.
