One of the features of UrbanSim is regression.
Here we provide an example of how to write the configuration that allows you to tinker with the regression for residential property values in UrbanSim for the SF Bay Area.
At the end you should be able to change the specification for regression for residential housing (hedonic regression). While its not required for you to have used R before, we occasionally refer to R's lm function , because its a standard that many people are familiar with.
