this disables the part of the test that checks for frozen distributions, so master doesn't have test errors in the run with the scipy 0.14 version.
I don't have currently scipy 0.14 available to look for a proper solution.
something went wrong, I didn't branch from master
TST: disable test failing with scipy 0.14.0
Coverage decreased (-0.02%) when pulling 92bef66 on josef-pkt:disable_tst_distribution_1864 into b257c7c on statsmodels:master.
BUG: add _ctor_param to TransfGen distributions
so that they can be frozen with scipy >= 0.14.
