This package includes several R functions. It can be used to simulate the state space model and estimate the parameters with bayesian method.
The model is:
y=H*beta_{t}+R, Beta_{t}=mu+fp*Beta_{t-1}+qq
The package may have problem. Welcome to email me at (link zz5m and virginia.edu with @) to discuss it.
