# Model Factories¶

All of these can be imported from halotools.empirical_models.

## HOD Model Factories¶

 HodModelFactory(**kwargs) Class used to build HOD-style models of the galaxy-halo connection. HodMockFactory([Num_ptcl_requirement, …]) Class responsible for populating a simulation with a population of mock galaxies based on an HOD-style model built by the HodModelFactory class.

## Subhalo Model Factories¶

 SubhaloModelFactory(**kwargs) Class used to build models of the galaxy-halo connection in which galaxies live at the centers of subhalos. SubhaloMockFactory(**kwargs) Class responsible for populating a simulation with a population of mock galaxies based on models generated by SubhaloModelFactory.
