Inducing sparsity and shrinkage in time-varying parameter models
Time-varying parameter (TVP) models have the potential to be over-parameterized,
particularly when the number of variables in the model is large. Global-local priors are …

Triple the gamma—A unifying shrinkage prior for variance and variable selection in sparse state space and TVP models
A Cadonna, S Frühwirth-Schnatter, P Knaus - Econometrics, 2020 - mdpi.com
Time-varying parameter (TVP) models are very flexible in capturing gradual changes in the
effect of explanatory variables on the outcome variable. However, in particular when the …
