As an intern with the local home builder’s association, you have been asked to analyze the state of the local housing market, which has suffered during a recent economic crisis. You have been provided two data sets in the file HousingBubble. The Pre- Crisisworksheet contains information on 1,978 single-family homes sold during the one-year period before the burst of the “housing bubble.” These 1,978 observations have been split into a training set (1,186 observations) and a validation set (792 observations). The Post-Crisisworksheet contains information on 1,657 single family homes sold during the one-year period after the burst of the housing bubble. These 1,657 observations have been split into a training set (994 observations) and a validation set (663 observations). The data in both the Pre-Crisisand Post-Crisis worksheets have been appended with the same set of 2,000 observations designated as a test set. This test set corresponds to homes currently for sale, and because they have not yet been sold, each of these 2,000 observation has an artificial value of zero for the sale price
