[7] 1. In a set of observations (x1,y1), ..., (xn, Yn) the regression model holds for (yi|xi) i.i.d. N(g(x;), ). In other words we can write ~ Yi = g(xi) + i, i = 1, 2,...,n, i.i.d. where 1 ~ N(0,0). Let Bo+ Bi if x c. 9(x) = { 10 + 312 In here c is a known constant. Derive M.L.E. for o, B and o. Calculate the distribution for Bo and B, the M.L.E. estimators for o and .
