    I don't believe there is one. The Gamma function is the analytic continuation, but it has poles at the negative integers.

    The first thing you would have to do is define this "negative factorial function". Where did you find a reference to a "negative factorial function"? If this was given in some text exercise how was the negative factorial function defined?
