%description
Provides tools for fitting continuous-time autoregressive (CAR) and
complex CAR (CZAR) models for irregularly sampled time series using an
exact Gaussian state-space formulation and Kalman filtering/smoothing.
Implements maximum-likelihood estimation with stable parameterizations of
characteristic roots, model selection via AIC, residual and spectral
diagnostics, forecasting and simulation, and extraction of fitted state
estimates. Methods are described in Wang (2013)
<doi:10.18637/jss.v053.i05>.
