Transdimensional hierarchical Bayesian inversion of phase and group velocity
Description
This code performs joint inversion of phase and group velocities applying transdimensional Bayesian inversion. 1-D earth model is parameterized using layer interface model. This code also allows to interact the chains so that faster convergence is achieved. For more details, we refer to the following publications:
