I just added the beta patch to my old script
This runs with scipy trunk from maybe a month ago. it saves 79
histograms in a sub-directory.
I haven't looked at it in a while, and I didn't update it yet with
what Skipper found out when he worked on this.
I have been working more on getting standard errors for the estimates,
using GenericLikelihoodModel which is in development in statsmodel,
which should give asymptotic or bootstrap and eventually profile
likelihood standard errors and confidence intervals for the parameter
estimates, and allows parameters to depend on some explanatory
(When I tried to do this this summer, I got stuck in the literature on
pareto distributions and power-laws.)
One of the main work for fitting is getting good starting values for
individual distributions, and I think Skipper went further than what I
have. It would be good if we can get this to work (with BSD).
