{{alias}}( x, v )
    Evaluates the natural logarithm of the cumulative distribution function
    (CDF) for a Student's t distribution with degrees of freedom `v` at a value
    `x`.

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

    If provided a non-positive value for `v`, the function returns `NaN`.

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

    v: number
        Degrees of freedom.

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

    Examples
    --------
    > var y = {{alias}}( 2.0, 0.1 )
    ~-0.493
    > y = {{alias}}( 1.0, 2.0 )
    ~-0.237
    > y = {{alias}}( -1.0, 4.0 )
    ~-1.677
    > y = {{alias}}( NaN, 1.0 )
    NaN
    > y = {{alias}}( 0.0, NaN )
    NaN
    > y = {{alias}}( 2.0, -1.0 )
    NaN


{{alias}}.factory( v )
    Returns a function for evaluating the natural logarithm of the cumulative
    distribution function (CDF) of a Student's t distribution with degrees of
    freedom `v`.

    Parameters
    ----------
    v: number
        Degrees of freedom.

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

    Examples
    --------
    > var mylogcdf = {{alias}}.factory( 0.5 );
    > var y = mylogcdf( 3.0 )
    ~-0.203
    > y = mylogcdf( 1.0 )
    ~-0.358
