Description Details Author(s) References See Also
This package is designed for time series data. Uses fast implementations to estimate Vector Autoregressive models and Vector Autoregressive models with Exogenous Inputs. For speedup, fastVAR can use multiple cpu cores to calculate the estimates. For very large systems, fastVAR uses Lasso penalty to return very sparse coefficient matrices. Regression diagnostics can be used to compare models, and prediction functions can be used to calculate the n-step ahead prediction.
Includes Canada data set from package vars to validate results.

LazyLoad: | yes |
Depends: glmnet Suggests: multicore |
Very few functions:
VAR - estimate a standard VAR model
VARX - estimate a standard VARX model with exogenous inputs
SparseVAR - use lasso penalty to estimate a VAR model
SparseVARX - use lasso penalty to estimate a VARX model
VAR.diag - get regression diagnostics for a VAR or VARX model
VAR, VARX, SparseVAR, and SparseVARX have accompanying prediction methods, which can be invoked by predict(one of the four VAR models, n.ahead)
