Exercise 4.5

[JoeMansley]

I think something is wrong in the solution to 4.5.

The log-likelihood is <=0 for any beta, but it's claimed that it tends to infinity.

[YuhangZhou88]

Thanks, you are correct.

In second equation, when beta-> infinity, the first summation converges to 0, wherease the second converges to infinity.

Thanks, you are correct.

In second equation, when beta-> infinity, the first summation converges to 0, wherease the second converges to infinity.

the second summation should be converging to zero, which is the max of the log likelihood
