Yeah, he is basically saying he copied that from the PcFiml/PcGive
manual by Doornik&Hendry. (multivariate ARCH-LM type test, I mean)
Should also be fairly straightforward, but not right now...
Attached is a prototype. Now this produces some results in the test
case, but it is really untested, please don't make this the standard
VAR-ARCH test output just yet.
Based on section 16.5.1 (essentially equation 16.5.1) from Helmut
Lütkepohl.
