MLE for discrete distributions: no fit() method on rv_discrete?

[Keith Braithwaite]

Hi,

I would like to find MLEs (and subsequently goodness of fit and so on) for empirical data against discrete distributions. I notice that scipy.stats.rv_discrete does not have the fit() method that scipy.stats.rv_continuous does. Is there a technical (either Pythonic or statistical) reason why not? If I roll my own am I going to get nonsense results?

Best Regards,

Keith
