%description
Build customized transfer function and ARIMA models with multiple
operators and parameter restrictions. Provides tools for model
identification, estimation using exact or conditional maximum likelihood,
diagnostic checking, automatic outlier detection, calendar effects,
forecasting, and seasonal adjustment. The new version also supports
unobserved component ARIMA model specification and estimation for
structural time series analysis.
