jobs of the economic statistician. It is he or she who is primarily responsible for collecting data on gross national product (GNP), employment, unem- ployment, prices, etc. The data thus collected constitute the raw data for econometric work. But the economic statistician does not go any further, not being concerned with using the collected data to test economic theories. Of course, one who does that becomes an econometrician.
Although mathematical statistics provides many tools used in the trade, the econometrician often needs special methods in view of the unique na- ture of most economic data, namely, that the data are not generated as the result of a controlled experiment. The econometrician, like the meteorolo- gist, generally depends on data that cannot be controlled directly. As Spanos correctly observes:
