{{alias}}( t, μ, s )
    Evaluates the moment-generating function (MGF) for a logistic distribution
    with location parameter `μ` and scale parameter `s` at a value `t`.

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

    If provided `s < 0`, the function returns `NaN`.

    Parameters
    ----------
    t: number
        Input value.

    μ: number
        Location parameter.

    s: number
        Scale parameter.

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

    Examples
    --------
    > var y = {{alias}}( 0.9, 0.0, 1.0 )
    ~9.15
    > y = {{alias}}( 0.1, 4.0, 4.0 )
    ~1.971
    > y = {{alias}}( -0.2, 4.0, 4.0 )
    ~1.921
    > y = {{alias}}( 0.5, 0.0, -1.0 )
    NaN
    > y = {{alias}}( 0.5, 0.0, 4.0 )
    Infinity
    > y = {{alias}}( NaN, 0.0, 1.0 )
    NaN
    > y = {{alias}}( 0.0, NaN, 1.0 )
    NaN
    > y = {{alias}}( 0.0, 0.0, NaN )
    NaN


{{alias}}.factory( μ, s )
    Returns a function for evaluating the moment-generating function (MGF)
    of a Logistic distribution with location parameter `μ` and scale parameter
    `s`.

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

    s: number
        Scale parameter.

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

    Examples
    --------
    > var mymgf = {{alias}}.factory( 10.0, 0.5 );
    > var y = mymgf( 0.5 )
    ~164.846
    > y = mymgf( 2.0 )
    Infinity
