Hi

I am using the ugarchspec function from the rgarch package to fit a mean
variance model jointly. Following is the code I'm using:

> spec = ugarchspec(variance.model = list(model="eGARCH",
garchOrder=c(1,1)), mean.model = list(armaOrder=c(1,1)))

On doing this, I get the following error:

Error in ugarchspec(variance.model = list(model = "eGARCH", garchOrder =
c(1,  :
  could not find function ".DistributionBounds"

Any help on why this is happening? any way to solve this?

Thanks
