PercentileRanks(self, xs) param error

[muxuezi]

PercentileRanks(self, xs) param is xs, but use x in function body, change x to xs

def PercentileRanks(self, xs):
    """Returns the percentile ranks of the values in xs.

    xs: potential value in the CDF

    returns: array of percentile ranks in the range 0 to 100
    """
    return self.Probs(**x**) * 100

BTW, thinkbayes2.py is too long to read hard, some submodules maybe helpful~
