从网上找到的程序套用出来的，不明白各变量什么含义，和从文献上看到的对应不上……求高手解释！

程序（来自pinggu一位同学的回复，找不到在哪了看的了，在此感谢该同学热心提供）：

open data 123.xls
data(format=xls,org=columns) / szgz szzs

compute n=2
dec vect[series] x(n)
compute i=0
dofor [string] s = 'szgz' 'szzs'
compute xrate=s,i=i+1
set x(i) = 100.0*log(%s(xrate)/%s(xrate){1})
end dofor

dec vect[series] eps(n)
dec vect fullbeta(4*n+2)

do i=1,n
garch(p=1,q=1,resids=r,hseries=h) / x(i)
set eps(i) = r/sqrt(h)
do j=1,4
compute fullbeta(n*(j-1)+i)=%beta(j)
end do j
end do i

compute b=.80,a=.10
maximize logl 2 *
