The simulation method implements a forward modeling approach for velocity and density fields. This method is part of the :py:mod:`flip.simulation` subpackage.
Note
This method is currently under construction. The subpackage structure is in place but the implementation is being developed in collaboration with other contributors.
The forward modeling simulation approach provides an alternative to the covariance-based method by directly simulating velocity and density fields. This allows for more flexible modeling of non-linear effects and complex survey geometries.
The simulation method shares the common modules of the flip package:
- :py:mod:`flip.power_spectra` for power spectrum computation.
- :py:mod:`flip.data_vector` for data vector handling.
- :py:mod:`flip.data` for test data.
The simulation method requires additional dependencies that can be installed via:
pip install flipcosmo[simulation]This installs JAX, JAXpm, JAXopt, jax-cosmo, and diffrax for differentiable simulation support.
