The Gamma distribution does asymptotically approach the normal distribution as the shape parameter increases. Your shape parameter is very large. One issue is that it looks like your `uminusr` data is truncated ("censored") to omit any values less than 1.8. The fitting procedure in `fit()` assumes that you are giving it uncensored data. That's driving it to make the left tail as low as possible and driving the Gamma to look more normal. -- Robert Kern _______________________________________________ SciPy-User mailing list [email protected] https://mail.python.org/mailman/listinfo/scipy-user
