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.
