Dear Jenn,
please find my solutions for task 1. I still have no access to the dropbox, but already
got my HUID number.
I supppose you are 5 to 6 hours behind in Boston. Thus 10 pm MEZ should be 5 pm your
time.
Regards and best wishes from Germany-
Joerg

Mmmmh, thanks for mailing your task to everybody? Please don't mix up
the "reply" with the "reply to mailinglist"-button, it's
disturbing
sometimes ...
Anyway, the Political Methodology-handbook arrived at the Coop! It's
about 27 dollars!
Cheers,
Tim

New subject: [gov2001-l] Last minute question
I was calculating sigmahat^2 in the following way:
ssq <- ((t(u)%*%u)/length(y)/3)%*%xtx^-1
That was going okay when I tried it with my made-up data. But with
the dataset I get this error:
Error in ((t(u) %*% u)/length(y)/3) %*% xtx^-1 :
non-conformable arguments
Why might that happen?

non-conformable arguments
Suggests that some of matrices you are trying to multiply are not
conformable. Recall from the matrix algebra review that you can only
multiply two matrices A and B iff A (l x k) and B (k x p). So check the
matrices, at least one of them has the wrong dimensions. Also notice that
both objects need to be matrices.

Could somebody make problem set 2 available? The problem set 2 folder
seems to be empty on the website. Thanks!
