Subject: How to get residuasl with arima0?
Date: Wed, 19 Sep 2001 15:19:07 -0300


	I know this is a basic question, but I've never used the 'ts'
package and
I'm having some problem with it. If I type, for example:
>fit1<-arima0(x , ...)
>resid(fit1)
the answer is 'NULL'. What is wrong? How to obtain residuals?

Thanks,

Marcos

There is no method of residuals() for an object of class "arima0".

Just use instead:

  fit1$resid
