s of degree :math:`n-1`
having knots evenly spaced from :math:`1` to :math:`n` [4]_ [5]_.

The Bates distribution, which represents the *mean* of statistically
independent, uniformly distributed random variables, is simply the
Irwin-Hall distribution scaled by :math:`1/n`. For example, the frozen
distribution ``bates = irwinhall(10, scale=1/10)`` represents the
distribution of the mean of 10 uniformly distributed random variables.

zÞ        Raises a ``NotImplementedError`` for the Irwin-Hall distribution because
        the generic `fit` implementation is unreliable and no custom implementation
        is available. Consider using `scipy.stats.fit`.
