In the paper a weighted quadratic variation based on a sequence of partitions for a class of Gaussian processes is considered. Conditions on the sequence of partitions and the process are established for the quadratic variation to converge almost surely and for a central limit theorem to be true. Also applications to bifractional and sub-fractional Brownian motion and the estimation o... https://www.hindigyanvishv.com/best-buy-Big-Sur-After-Rain-Hand-Soap-amazing-deal/
