Does asymptotic linearity of the regression extend
to stable domains of attraction?

Abstract:
Hardin, Samorodnitsky, Taqqu (1991) have
shown that the regression is typically asymptotically linear when is an -stable random vector with . We provide
necessary and
sufficient conditions for asymptotic linearity of where
is an -stable random vector and is
a random variable, independent of
, such that is in the domain of normal attraction
of X.
Asymptotic linearity does not always hold even when is
linear. For some
distributions of , the asymptotic rate of
fluctuates.
