Columns: rownames, the row number; year, 1978 or 1981; y81, 1 for a 1981 sale; price, the selling price in dollars; rprice, the price in 1978 dollars (real price); lprice and lrprice, their natural logs; nearinc, 1 if the house is within 3 miles (15,840 feet) of the incinerator site; y81nrinc, y81 times nearinc; dist, distance from the incinerator site in feet, and ldist its log; y81ldist, y81 times ldist; age, the age of the house in years, and agesq its square; rooms, number of rooms; baths, number of bathrooms; area, square footage of the house, and larea its log; land, square footage of the lot, and lland its log; intst, distance from the interstate in feet, lintst its log and lintstsq the square of that log; cbd, distance from the central business district in feet; nbh, the neighbourhood (1 to 6); wind, the percentage of time the wind blows from the incinerator toward the house.

The text of that page states the same estimate, 11,863.90 in absolute value, as the difference of the 1981 and 1978 near-incinerator price gaps. Data facts checked before any estimate: 321 sales (179 in 1978, 142 in 1981), no missing values in the columns used.
