Returns the residuals at the final parameter estimate.
A double
array of length z.Length - max(arLags[i]) + length
containing the residuals (including backcasts) at the final parameter estimate point in the first z.Length - max(arLags[i]) + nb
, where nb
is the number of values backcast.
Note that the Compute
method must be invoked first before invoking this method. Otherwise, the method throws a NullReferenceException
exception.This method is only applicable using least-squares algorithm.
