{{alias}}( x, μ, β )
    Evaluates the logarithm of the cumulative distribution function (CDF) for a
    Gumbel distribution with location parameter `μ` and scale parameter `β` at a
    value `x`.

    If provided `NaN` as any argument, the function returns `NaN`.

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

    Parameters
    ----------
    x: number
        Input value.

    μ: number
        Location parameter.

    β: number
        Scale parameter.

    Returns
    -------
    out: number
        Evaluated logCDF.

    Examples
    --------
    > var y = {{alias}}( 10.0, 0.0, 3.0 )
    ~-0.036
    > y = {{alias}}( -2.0, 0.0, 3.0 )
    ~-1.948
    > y = {{alias}}( 0.0, 0.0, 1.0 )
    ~-1.0
    > y = {{alias}}( NaN, 0.0, 1.0 )
    NaN
    > y = {{alias}}( 0.0, NaN, 1.0 )
    NaN
    > y = {{alias}}( 0.0, 0.0, NaN )
    NaN
    // Negative scale parameter:
    > y = {{alias}}( 0.0, 0.0, -1.0 )
    NaN


{{alias}}.factory( μ, β )
    Returns a function for evaluating the logarithm of the cumulative
    distribution function (CDF) of a Gumbel distribution with location parameter
    `μ` and scale parameter `β`.

    Parameters
    ----------
    μ: number
        Location parameter.

    β: number
        Scale parameter.

    Returns
    -------
    logcdf: Function
        Logarithm of cumulative distribution function (CDF).

    Examples
    --------
    > var myLCDF = {{alias}}.factory( 2.0, 3.0 );
    > var y = myLCDF( 10.0 )
    ~-0.069
    > y = myLCDF( 2.0 )
    ~-1.0
