source

Daniel McMillen. Sales data were provided originally by the Illinois Department of Revenue. Structural characteristics are drawn from the 1997 assessment file from the Cook County Assessor's Office.

Details

Includes all sales of single-family homes on the Far North Side of Chicago listed in the cleaned Illinois Department of Revenue file for 1995. A matched sample is created from comparable 2005 sales using the MatchIt package. Matches are created based on propensity scores estimated using a logit model for the probability that a home sold in 2005 rather than 1995. The commands used to create the matched sample are the following: hedonic$carea <- as.factor(hedonic$cname) m.out <- matchit(y~lnland + lnbldg + rooms + bedrooms + bathrooms + centair + fireplace + brick + garage1 + garage2 + dcbd + elstop + lake + rr + yrbuilt + carea + latitude + longitude, data=hedonic,method="nearest",discard="both") mdata <- match.data(m.out) attach(mdata) matchdata <- data.frame(year, lnland, lnbldg, rooms, bedrooms, bathrooms, centair, fireplace, brick, garage1, garage2, dcbd, rr, yrbuilt, carea, latitude, longitude, lnprice) The elstop and lake variables, which are not included here, indicate whether a home is within .25 miles of and EL stop and within .5 miles of Lake Michigan.
