为什么我用课程的程序一模一样的都时老出错呢?有没有老师可以解答啊?那个program里面的东西不是直接对着用就可以吗?还要自己变动的吗? shouyilv=read.table(file="e:/shouyilv.txt")
> colnames(shouyilv)=c("huilv","zhishu")
> shouyilv.ewma=mgarch(shouyilv~1,formula.var~ewma1,)
Problem: Couldn't find a function definition for "mgarch"
Use traceback() to see the call stack
都是出现这种问题,请问有没有老师可以解答?
