Given a nonstationary process X_t (with |rho|>1), we examine instead (1/n)*ln|X_n| and study the distribution of ln|X_n|-n*ln|rho|.8 pages; introduced corrections in section 3Dynamical SystemsProbabilityStatistics Theory62M10 (Primary); 11Y60, 34D08, 37H10, 60H10, 60J05, 65C50 (Secondary)Another Look at AR(1)text
