Author: Source: Unknown - Please cite: Data from StatLib (ftp stat.cmu.edu/datasets) The infamous Longley data, "An appraisal of least-squares programs from the point of view of the user", JASA, 62(1967) p819-841. Variables are: Number of people employed (usually the y variable) GNP implicit price deflator GNP Unemployed Armed forces Non-institutionalized population >=14 years of age Year Employment is being treated as the class attribute.
