{{alias}}( x, λ )
    Evaluates the moment-generating function (MGF) for a Poisson distribution
    with mean parameter `λ` at a value `x`.

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

    If provided a negative value for `λ`, the function returns `NaN`.

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

    λ: number
        Mean parameter.

    Returns
    -------
    out: number
        Evaluated MGF.

    Examples
    --------
    > var y = {{alias}}( 1.0, 1.5 )
    ~13.163
    > y = {{alias}}( 0.5, 0.5 )
    ~1.383
    > y = {{alias}}( NaN, 0.5 )
    NaN
    > y = {{alias}}( 0.0, NaN )
    NaN
    > y = {{alias}}( -2.0, -1.0 )
    NaN


{{alias}}.factory( λ )
    Returns a function for evaluating the moment-generating function (MGF) of a
    Poisson distribution with mean parameter `λ`.

    Parameters
    ----------
    λ: number
        Mean parameter.

    Returns
    -------
    mgf: Function
        Moment-generating function (MGF).

    Examples
    --------
    > var myMGF = {{alias}}.factory( 2.0 );
    > var y = myMGF( 0.1 )
    ~1.234
