GVARest: Estimate country-specific VAR in a GVAR setting

Description

Estimate country-specific VAR in a GVAR setting

Usage

GVARest(data,p,FLag, lag.max, type="const", ic,weight.matrix=NULL)

Arguments

data

Dataframe is a strictly balanced panel data format,the first column is cross-section ID,and the second column is Time. For the sake of identification, both columns must be named by, respectively, id and Time.

p

The number of lag for Xt matrix.

FLag

The number of lag for foreign variables in country-specific VAR

lag.max

The maximal number of lag for estimating country-specific VAR

type

Model specificaiton for VAR. As in package vars, we have four selection: "none","const","trend", "both".

ic

Information criteria for optimal lag.As in package vars, we have four selection: "AIC", "HQ", "SC", and "FPE".

weight.matrix

Bilateral trade weight matrix for computing foreign variables. If the computation of foreign variables are weighted by one weighting matrix, weight.matrix must be a "data.frame". If the computation of foreign variables are weighted on a year-to-year basis, then weight.matrix must be a "list, with the same length as the weighting frequency.

Value

gvar

Country-specific GVAR output list

White

Coefficient estimates with White robust covariance

NWHAC

Coefficient estimates withNewy-West robust covariance

p

Number of lags for endogeneous variables in VAR

K

Number of lags for Ft variables in VAR

type

Model specificaiton. As in package vars, we have four selection: "none","const","trend", and "both".
