pystable

Python wrapper for the libstable C library.

Example

To fit with ML estimation:

import pystable

init_fit = {'alpha': 2, 'beta': 0, 'sigma': 1, 'mu': 0,
            'parameterization': 1}
dist = pystable.create(init_fit['alpha'], init_fit['beta'],
                       init_fit['sigma'], init_fit['mu'],
                       init_fit['parameterization'])

pystable.fit(dist, data, len(data))
fit_params = [dist.contents.alpha, dist.contents.beta,
              dist.contents.sigma, dist.contents.mu_0, dist.contents.mu_1]
