{{alias}}( [k, λ] )
    Returns an Erlang distribution object.

    Parameters
    ----------
    k: number (optional)
        Shape parameter. Must be a positive integer. Default: `1.0`.

    λ: number (optional)
        Rate parameter. Must be greater than `0`. Default: `1.0`.

    Returns
    -------
    erlang: Object
        Distribution instance.

    erlang.k: number
        Shape parameter. If set, the value must be a positive integer.

    erlang.lambda: number
        Rate parameter. If set, the value must be greater than `0`.

    erlang.entropy: number
        Read-only property which returns the differential entropy.

    erlang.kurtosis: number
        Read-only property which returns the excess kurtosis.

    erlang.mean: number
        Read-only property which returns the expected value.

    erlang.mode: number
        Read-only property which returns the mode.

    erlang.skewness: number
        Read-only property which returns the skewness.

    erlang.stdev: number
        Read-only property which returns the standard deviation.

    erlang.variance: number
        Read-only property which returns the variance.

    erlang.cdf: Function
        Evaluates the cumulative distribution function (CDF).

    erlang.logpdf: Function
        Evaluates the natural logarithm of the probability density function
        (PDF).

    erlang.mgf: Function
        Evaluates the moment-generating function (MGF).

    erlang.pdf: Function
        Evaluates the probability density function (PDF).

    erlang.quantile: Function
        Evaluates the quantile function at probability `p`.
