The S&P/Case-Shiller Home Price Indices provide measures of the U.S. residential housing market. They track changes in the value of residential real estate nationally and in 20 metropolitan regions. (Some of these indices are actually traded on the Chicago Mercantile Exchange). The dataset Case-Shiller gives the monthly index values for each of the 20 cities tracked by the Case-Shiller index and two national composite series. Examine these values and write a report on them. Some suggestions: First consider the Composite.20 series, which combines (seasonally adjusted) data for the 20 cities. Describe the distribution of prices overall, then look at a timeseries plot and discuss the trend over time especially the period from 2007 to 2008. Then select several cities to compare. For example, you might compare Miami, Boston, and Detroit. Write a report discussing how trends in housing prices changed over time and how these changes differed from city to city.
