%description
Provides efficient Markov chain Monte Carlo (MCMC) algorithms for dynamic
shrinkage processes, which extend global-local shrinkage priors to the
time series setting by allowing shrinkage to depend on its own past. These
priors yield locally adaptive estimates, useful for time series and
regression functions with irregular features. The package includes full
MCMC implementations for trend filtering using dynamic shrinkage on signal
differences, producing locally constant or linear fits with adaptive
credible bands. Also included are models with static shrinkage and
normal-inverse-Gamma priors for comparison. Additional tools cover dynamic
regression with time-varying coefficients and B-spline models with
shrinkage on basis differences, allowing for flexible curve-fitting with
unequally spaced data. Some support for heteroscedastic errors, outlier
detection, and change point estimation. Methods in this package are
