thinkstats2.EvalLognormalCdf TypeError #35

Closed dkandalov closed 2 years ago

dkandalov commented 8 years ago

When running thinkstats2.EvalLognormalCdf(df.income, mu=0, sigma=1) python fails with

thinkstats2.EvalLognormalCdf(df.income, mu=0, sigma=1)
  File "/path/ThinkStats2/code/thinkstats2.py", line 1895, in EvalLognormalCdf
    return stats.lognorm.cdf(x, loc=mu, scale=sigma)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/scipy/stats/distributions.py", line 1329, in cdf
    args, loc, scale = self._parse_args(*args, **kwds)
TypeError: _parse_args() takes at least 2 arguments (3 given)

If I change EvalLognormalCdf to not use named args, it seems to work, i.e. return stats.lognorm.cdf(x, mu, sigma).

I will look into this as soon as I can.

Thanks!
