Predicting the past - Tilburg University, The Netherlands

I am much impressed by all the scientific terms he uses:
Matrix calculus and asymptotic theory and such.
I admit that quite a lot of it perplexes and confuses,
And it wouldn’t make a difference if it had been in Dutch.
Intuition also gives me indigestion,
And the question whether models that you use in your research are right or wrong
for me is certainly too difficult a question.
Oh, the orator casts a magic spell,
But the things he says don’t even ring a bell.
No, as far as I can tell,
Magnus just does not explain it very well.
I have always been intrigued by the econometric sector,
And I can assure you that there’s little that I wouldn’t give
If they made me grasp the essence of a matrix or a vector
Or indeed the underlying concept of derivative.
It is also quite beyond my comprehension
That, whenever you employ a differential, then the differential of a matrix is a matrix
of the same dimension.
I am no statistician and confess
That I cannot even make a learned guess.
And I may know even less
After Jan’s valedictory address.
