further arguments passed to or from other methods.

Details

The log-likelihood for the calculation of the information criteria is obtained by

LL=1Ri=1R(t=1TK2ln2π12lnΣt(i)12(ut(i)(Σt(i))1ut(i))LL = \frac{1}{R} \sum_{i = 1}^{R} \left( \sum_{t = 1}^{T} -\frac{K}{2} \ln 2\pi - \frac{1}{2} \ln |\Sigma_t^{(i)}| -\frac{1}{2} (u_t^{{(i)}\prime} (\Sigma_t^{(i)})^{-1} u_t^{(i)} \right)

, where ut=ytμtu_t = y_t - \mu_t. The Akaike, Bayesian and Hannan–Quinn (HQ) information criteria are calculated as

AIC=2(Kp+Ms+N)2LLAIC = 2 (Kp + Ms + N) - 2 LL

,

BIC=(Kp+Ms+N)ln(T)2LLBIC = (Kp + Ms + N) ln(T) - 2 LL

and

HQ=2(Kp+Ms+N)ln(ln(T))2LLHQ = 2 (Kp + Ms + N) ln(ln(T)) - 2 LL

, respectively, where KK is the number of endogenous variables, pp the number of lags of endogenous variables, MM the number of exogenous variables, ss the number of lags of exogenous variables, NN the number of deterministic terms and TT the number of observations.

Value

summary.bvarlist returns a table of class "summary.bvarlist".
