This classic dataset of labor statistics was one of the first used to test the accuracy of least squares computations. The response variable (y) is the Total Derived Employment and the predictor variables are GNP Implicit Price Deflator with Year 1954 = 100 (x1), Gross National Product (x2), Unemployment (x3), Size of Armed Forces (x4), Non-Institutional Population Age 14 & Over (x5), and Year (x6).
