return rv(name, GammaDistribution, (k, theta))
r"""
    Create a continuous random variable with a Gamma distribution.

    The density of the Gamma distribution is given by

    .. math::
        f(x) := \frac{1}{\Gamma(k) \theta^k} x^{k - 1} e^{-\frac{x}{\theta}}

    with :math:`x \in [0,1]`.

    Parameters
    ==========

    k : Real number, `k > 0`, a shape
    theta : Real number, `\theta > 0`, a scale

    Returns
    =======

    A RandomSymbol.
