I was using the rugarch package to fit an ARMA-GARCH model with multiple external regressors. But there is an error message that says:

Error in svd(na.omit(xreg)) : a dimension is zero

I'm wondering what is causing this error. Thanks!

  • Please do not post images of code, it is easier for others to help you if they can copy/paste your code, run it, and reproduce your problem.

  1. testdata_1 should be in matrix format.

  2. There should be no Na's

  3. Check if there's data inside testdata_1[,-c(1:2)]
