For the exponential regression model of Section 7.5.1, show that the O(n−1

) bias of βˆ is bias (ˆβ) = −(XTX)

−1XTV/2.

Show that, for a simple random sample of size 1, the bias is exactly −γ, where

γ = 0.57721 is Euler’s constant. Find the exact bias for a simple random sample of size n and compare with the approximate formula.
