{{alias}}( p )
    Evaluates the logit function.

    Let `p` be the probability of some event. The logit function is defined as
    the logarithm of the odds `p / (1-p)`.

    If `p < 0` or `p > 1`, the function returns `NaN`.

    Parameters
    ----------
    p: number
        Input value.

    Returns
    -------
    y: number
        Function value.

    Examples
    --------
    > var y = {{alias}}( 0.2 )
    ~-1.386
    > y = {{alias}}( 0.9 )
    ~2.197
    > y = {{alias}}( -4.0 )
    NaN
    > y = {{alias}}( 1.5 )
    NaN
    > y = {{alias}}( NaN )
