Consider the fractional Brownian Motion (fBM) $B^H=\{B^H(t): t \in [0,1] \}$ with Hurst index $H\in (0,1)$. We construct a probability space supporting both $B^H$ and a fully simulatable process $\hat B_{\epsilon}^H $ such that $$\sup_{t\in [0,1]}|B^H(t)-\hat B_{\epsilon}^H(t)| \le \epsilon$$ with probability one for any user specified error parameter $\epsilon>0$. When $H>1/2$, we further enhance our error guarantee to the $\alpha$-Holder norm for any $\alpha \in (1/2,H)$. This enables us to…

$\varepsilon $-strong simulation of the convex minorants of stable processes and meanders

Using marked Dirichlet processes we characterise the law of the convex minorant of the meander for a certain class of L\'evy processes, which includes subordinated stable and symmetric L\'evy

Rate of convergence and asymptotic error distribution of Euler approximation schemes for fractional diffusions

For a stochastic differential equation(SDE) driven by a fractional Brownian motion(fBm) with Hurst parameter $H>\frac{1}{2}$, it is known that the existing (naive) Euler scheme has the rate of

On Optimal Exact Simulation of Max-Stable and Related Random Fields

TLDR
The random field M(t) is considered, for a set $T\subset \mathbb{R}^{m}$, where $(X_{n})$ is an iid sequence of centered Gaussian random fields on $T$ and $0 0$ with complexity $o(c(d)\,d^{\epsilon })$, where $M$ can be a.s. converging series representation.

Fast and Exact Simulation of Stationary Gaussian Processes through Circulant Embedding of the Covariance Matrix

TLDR
This paper shows that for many important correlation functions in geostatistics, realizations of the associated process over $m+1$ equispaced points on a line can be produced at the cost of an initial FFT of length $2m$ with each new realization requiring an additionalFFT of the same length.

Abstract In this article, we derive the exact rate of convergence of some approximation schemes associated to scalar stochastic differential equations driven by a fractional Brownian motion with

Optimal series representation of fractional Brownian sheets

For 0 < γ < 2 let B γ be a d–dimensional γ–fractional Brownian sheet with index set [0, 1] and let (ξk)k≥1 be an i.i.d. sequence of standard normal random variables. We prove the existence of

This article focuses on simulating fractional Brownian motion (fBm). Despite the availability of several exact simulation methods, attention has been paid to approximate simulation (i.e., the output

TLDR
This paper presents the first Bernoulli factory for f(p) = Cp with bounds on $\mathbb{E}[T]$ as a function of the input parameters, which is optimal up to a constant in the running time.

Self-similar traffic generation: the random midpoint displacement algorithm and its properties

TLDR
An approximate FBM generation method known as the random midpoint displacement (RMD) algorithm is considered and its analysis indicates that (i) RMD is attractive for qualitative studies and (ii) for quantitative studies the parameters of the generated traces may differ from their target values.
