Abstract
We consider a series of bilinear sequences
, with i.i.d. εk and small bilinearity coefficients bn = βn−1/2 and show that under the standard normalization they converge to a diffusion process Yβ. We provide an explicit form of Yβ, investigate the moments of Yβ, and study the limiting behavior of some other quantities related to X (n)k and important for statistical applications. Bibliography: 5 titles.
