An economist is a trained professional paid to guess wrong about the
economy.
An econometrician is a trained professional paid to use computers to guess
wrong about the economy.
"Econometric theory is like an exquisitely balanced French recipe, spelling
out precisely with how many turns to mix the sauce, how many carats of spice
to add, and for how many milliseconds to bake the mixture at exactly 474
degrees of temperature. But when the statistical cook turns to raw materials, he
finds that hearts of cactus fruit are unavailable, so he substitutes chunks
of cantaloupe; where the recipe calls for vernicelli he uses shredded wheat;
and he substitutes green garment dye for curry, ping-pong balls for turtle's
eggs, and for Chaliougnac vintage 1883, a can of terpentine. "
S. Valvanis (1959), Econometrics.
