We investigate the asymptotic properties of the sequential maximum likelihhod estimator of the drift parameter for fractional Ornstein-Uhlenbeck type process satisfying a linear stochastic differential equation driven by fractional Brownian motion.

Fractal-skeletal based channel network (F-SCN) model, which describes how the boundary of the basin constrains the channel network evolution, produces a channel network pattern that obeys Horton's laws. The statistical features of this model conform well with real networks. For this F-SCN that depends on general shape of the initiator-basin, generating… (More)

We study maximal inequalities for demisubmartingales and N-demisupermartingales and obtain inequalities between dominated demisub-martingales. A sequence of partial sums of zero mean associated random variables is an example of a demimartingale and a sequence of partial sums of zero mean negatively associated random variables is an example of a… (More)

In this paper, we prove common fixed point theorems for six self maps by using weakly compatibility, without appeal to continuity in fuzzy metric space. Our results extend, generalized several fixed point theorems on metric and fuzzy metric spaces. INTRODUCION In 1965, the concept of fuzzy sets was intraduced by Zadeh[23].Following the concept of fuzzy… (More)

Let {Yn, n≥ 1} be a sequence of nonmonotonic functions of associated random variables. We derive a Newman and Wright (1981) type of inequality for the maximum of partial sums of the sequence {Yn, n≥ 1} and a Hajek-Renyi-type inequality for nonmonotonic functions of associated random variables under some conditions. As an application, a strong law of large… (More)

SUMMARY. Uniform approximations for families of stochastic integrals of Rubin-Fisk-Stratonovich type and Ito type are studied. It is shown that the approximants of Rubin-Fisk-Stratonovich type obtained from partitions of equal size converge faster to the corresponding stochastic integral than the approximants of Ito type for such partitions converge to the… (More)
