    Returns the variance of a Pareto (Type I) distribution.

    If `0 < α <= 2` and `β > 0`, the function returns positive infinity.

    If `α <= 0` or `β <= 0`, the function returns `NaN`.

    If `α` or `β` is `NaN`, the function returns `NaN`.

    Parameters
    ----------
    α: number
        Shape parameter.

    β: number
        Scale parameter.

    Returns
    -------
    out: number
        Variance.

    Examples
    --------
    > var v = {{alias}}( 0.8, 1.0 )
    Infinity
    > v = {{alias}}( 4.0, 12.0 )
    32.0
    > v = {{alias}}( 8.0, 2.0 )
