I get the error shown below trying to run a DCC GARCH Model. How can I correct this? I tried to use abs(X) on each variable but it still does not work.

Thanks for all advice in advance.

The error message is clear: The input of eig() cannot contain NaN or Inf.

Without seeing your code, the readers cannot guess, where the NaN or Inf are coming from and how you could avoid this problem. Why do you assume that abs(X) helps and what does "on each variable" mean?
