1.Econometrics deals with the measurement of economic relationships which are stochastic or random. The simplest form of economic relationships between two variables X and Y can be represented by:
; where
are regression parameters and
the stochastic disturbance term
Justify the reasons for the insertion of U-term in the model?
2.The following data refers to the demand for money (M) and the rate of interest (R) in for eight different economics:
Demand for money (M) (In billions)

a.Assuming a relationship, obtain the OLS estimators ofand
b.Calculate the coefficient of determination for the data and interpret its value
c.If in a 9th economy the rate of interest is R=8.1, predict the demand for money (M) in this economy.
