19.1. (a) The regression in the matrix form is

Y = Xb + U

(b) The null hypothesis is

Rb = r

versus Rb ¹ r with

R = ( 0 0 1 ) and r = 0.

The heteroskedasticity-robust F-statistic testing the null hypothesis is

-1
F = (Rβˆ - r)¢ é RΣ
ˆ R¢ù (Rβˆ - r )/q
ë βˆ û

With q = 1. Under the null hypothesis,

d
F→ Fq, ∞ .

We reject the null hypothesis if the calculated F-statistic is larger than the critical
value of the Fq ,¥ distribution at a given significance level.

19.2. (a) The sample size n = 20. We write the regression in the matrix from:

Y = Xb + U

with

⎛ Y1 ⎞ ⎛ X 2,1 ⎞

⎜ Y2 ⎟ ⎜ ⎟
Y=⎜ ⎟ ⎜ 1 X 1, 2 X 2, 2 ⎟
