Hyperparameters:
----------------
moves: list
Consult the [emcee documentation](https://emcee.readthedocs.io/en/stable/user/moves/).
Algorithm used for updating the coordinates of walkers in an ensemble sampler. By default, pySODM uses a differential evolution move 25% of the time, a differential evolution snooker move 25% of the time, and a kernel-density estimate move 50% of the time. Consult the [emcee documentation](https://emcee.readthedocs.io/en/stable/user/moves/).
backend: emcee.backends.HDFBackend
Backend of a previous sampling experiment. If a backend is provided, the sampler is restarted from the last iteration of the previous run. Consult the [emcee documentation](https://emcee.readthedocs.io/en/stable/user/backends/).
progress: bool
