All distributions from SciPy's 'stats' module can be used with this class.

>>> import numpy as N
>>> from scipy import stats
>>> from mvpa.clfs.stats import FixedNullDist
>>>
>>> dist = FixedNullDist(stats.norm(loc=2, scale=4))
>>> dist.p(2)
0.5
>>>
>>> dist.cdf(N.arange(5))
array([ 0.30853754,  0.40129367,  0.5       ,  0.59870633,  0.69146246])
>>>
>>> dist = FixedNullDist(stats.norm(loc=2, scale=4), tail='right')
>>> dist.p(N.arange(5))
array([ 0.69146246,  0.59870633,  0.5       ,  0.40129367,  0.30853754])
