Web13 de jan. de 2024 · presents evidence for the importance of sparsification and shrinkage in TVP regression models using different data configurations, priors, numbers of regressors, and sample sizes. The DGP described above is modified to reflect varying degrees of sparsity. These different sparsity levels are labeled sparse (with 90% zeros in α ), … WebJuly 2024 Update. As of July 2024 there are a few changes to prior distributions: Except for in default priors, autoscale now defaults to FALSE.This means that when specifying custom priors you no longer need to manually set autoscale=FALSE every time you use a distribution.. There are minor changes to the default priors on the intercept and (non …
