%description
State space modelling is an efficient and flexible framework for
statistical inference of a broad class of time series and other data. KFAS
includes computationally efficient functions for Kalman filtering,
smoothing, forecasting, and simulation of multivariate exponential family
state space models, with observations from Gaussian, Poisson, binomial,
negative binomial, and gamma distributions. See the paper by Helske (2017)
<doi:10.18637/jss.v078.i10> for details.
