sampleBTF_reg | R Documentation |
Compute one draw of the T x p
state variable beta
in a DLM using back-band substitution methods.
This model is equivalent to the Bayesian trend filtering (BTF) model applied to p
dynamic regression coefficients corresponding to the design matrix X
,
assuming appropriate (shrinkage/sparsity) priors for the evolution errors.
