%description
Maximum likelihood estimation of smooth transition vector autoregressive
models with various types of transition weight functions, conditional
distributions, and identification methods. Constrained estimation with
various types of constraints is available. Residual based model
diagnostics, forecasting, simulations, and calculation of impulse response
functions, generalized impulse response functions, and generalized
forecast error variance decompositions. See Heather Anderson, Farshid
