Abstract
In 2010 J.M. Bardet and D. Surgailis [1] have introduced the increment ratio (IR) statistic which measures the roughness of random paths. It was shown that this statistic was applicable in the cases of diffusion processes driven by the standard Brownian motion, certain Gaussian processes and the Lévy process. This paper shows that the IR statistic can be applied to estimate the Hurst index H of the fractional geometric Brownian motion.
 
2010 m. J.M. Bardet ir D. Surgailis [1] įvedė pokyčių santykio (IR) statistiką, kuri matuoja atsitiktinio proceso trajektorijų šiurkštumą. Jie parodė, kad ši statistika gali būti taikoma difuziniams procesams, valdomiems standartinio Brauno judesio, tam tikriems Gauso procesams ir Lévy procesams. Šiame straipsnyje įrodoma, kad IR statistika gali būti taikoma trupmeninio geometrinio Brauno judesio Hursto indekso H vertinimui.
