%description
Determining potential output and the output gap - two inherently
unobservable variables - is a major challenge for macroeconomists.
'sectorgap' features a flexible modeling and estimation framework for a
multivariate Bayesian state space model identifying economic output
fluctuations consistent with subsectors of the economy. The proposed model
is able to capture various correlations between output and a set of
aggregate as well as subsector indicators. Estimation of the latent states
and parameters is achieved using a simple Gibbs sampling procedure and
various plotting options facilitate the assessment of the results. For
details on the methodology and an illustrative example, see Streicher
(2024)
