It has been shown before that when the randomization is bounded, the so-called odd-occupancy process scales to a fractional Brownian motion with Hurst index beta/2 in (0,1/2). We show here that when the randomization is heavy-tailed with index alpha in (0,2), then the odd-occupancy process scales to a (beta/alpha)-self-similar symmetric alpha-stable process with stationary increments.en-USinifinite urn schemeregular variationstable processself-similar processfunctional central limit theorempreprint
