Hmm. I don't think scipy needs to know about your distribution per se. You just need to be able to pass it to the probplot function via the `dist` parameter. Per the docs ( https://docs.scipy.org/doc/scipy-0.14.0/reference/generated/scipy.stats.probplot.html ): scipy.stats.probplot(*x*, *sparams=()*, *dist='norm'*, *fit=True*, *plot=None*)[source] <http://github.com/scipy/scipy/blob/v0.14.0/scipy/stats/morestats.py#L296> [snip] *dist* : str or stats.distributions instance, optional Distribution or distribution function name. The default is ‘norm’ for a normal probability plot. Objects that look enough like a stats.distributions instance (i.e. they have a ppf method) are also accepted.
