The essence of the matter is that Jarque-Bera uses asymptotic results
regardless of sample size for a problem in which convergence to those
results is very slow. This approach is decades out of date and I am
surprised that StataCorp support the test without a warning. The
Doornik-Hansen test, for example, looks much more satisfactory. This
was added in Stata 11 after Jarque-Bera was added.
