11. The following statistical model is postulated for representing the relationship between real aggregate disposable income and real aggregate expenditure on nondurable goods:

Yj = exp(pi + {32Xj + Ej)

Problems where Yi = real aggregate expenditure on nondurables in period i measured in billions of dollars, Xi = real aggregate disposable income in period i, measured in billions of dollars, and S,iS are 1"1 d,W'l th Si + a b ~ ba1q a)sia -I

There are 100 observations, (YI, xII, ... , (YIOO, XIOO) available to estimate the values of /31, /32, and a2 = vaI(si).
