参数怎么看?
这个作者有解释
# a bit complicated but following explanation will be useful hopefully ...
前面那个问题已经明白了,第二个还是不懂
> summary(est)
Length Class Mode
eps 3 data.frame list
series.length 1 -none- numeric
estimation.time 1 difftime numeric
total.time 1 difftime numeric
order 2 -none- numeric
estimation 6 -none- list
aic 1 -none- numeric
asy.se.coef 3 -none- list
est.params 3 -none- list
cor 3 -none- list
sd 3 -none- list
H.estimated 1000 -none- list
eigenvalues 9 -none- numeric
uncond.cov.matrix 9 -none- numeric
residuals 3 -none- list
这个是出来的结果
hessian=mod$cov$B
#observed Fisher information matrix=invert the Hessian
oi=solve( hessian)
se<-sqrt(diag(oi)) #Std.Error
se
这几句不懂?这里面的cov在BEKK里面应该是什么啊,是协方差矩阵吗?BEKK的结果只有给出参数系数啊?
