estimator.nd.TUniform

class estimator.nd.TUniform(b, n=None)

TUniform distribution ∈ ZZ ∩ [-2**b, 2**b], endpoints inclusive. This distribution samples the two end-points with probability 1/2**(b+2) and the intermediate points with probability 1/2**(b+1).

As an example, with b=0 this distribution samples ±1 each with probability 1/4 and 0 with probability 1/2.

EXAMPLE:

>>> from estimator import *
>>> ND.TUniform(0)
D(σ=0.71)
>>> ND.TUniform(10)
D(σ=591.21)

__call__(**kwargs)

Call self as a function.
