come and household size in affecting household
beef expenditures may vary substantially among
different types of beef. Judging from the partial
R2s, household size was found to be a more sig-
nificant factor than income in determining ex-
penditures for ground beef and beef roasts, but
the opposite was true on expenditure for beef
steaks.
Although the analysis has been limited to beef
expenditures, the same procedure and principles
are applicable to other commodities. It would be
desirable to extend the investigation with a na-
tional data base and expand the model to incor-
porate not only the size of household, but also
the household composition and other related so-
cioeconomic variables.
