Confidence Interval #2
Dear all,
I am so sorry that I cannot install the Chinese character entry add-in here.
Plz give me some ideas of solving this problem.
Thx a million :)
Let Y = Xβ + ε,where ε N ( 0,σ2IN),and
β is a p-dimensional vector,with N=10 and p=3.
Given y'y = 58,and given the following normal equations.
4β1(hat) + 2β2(hat) - 2β3(hat) = 4
2β1(hat) + 2β2(hat) + β3(hat) = 7
-2β1(hat) + β2(hat) +6β3(hat) = 9
a.Find the least squares estimates of β and σ2.
b.What are the estimates of β1,β2,β3,β1-β2,and β1+β3?
c.Assume that the errors have a normal distribution.
Construct 95% confidence intervals for β1,β2,β3,β1-β2,and β1+β3.

你可以把系统重装一下,直接装中文版的操作系统.省得再install the Chinese character entry add-in了 .
