Spectral domain likelihoods for Bayesian inference in time-varying parameter models

O Gustafsson, M Villani, R Kohn - arXiv preprint arXiv:2411.14010, 2024 - arxiv.org
Inference for locally stationary processes is often based on some local Whittle-type
approximation of the likelihood function defined in the frequency domain. The main reasons …
