We derive an explicit expression for the probability density function of the mth numerical derivative of a stochastic variable. It is shown that the proposed statistics can analytically be obtained based on the original probability characteristics of the observed signal in a simple manner. We argue that this allows estimating the statistical parameters of the original distribution and further, to simulate the noise contribution in the original stochastic process so that the noise component is… Expand

Noise-level determination for discrete spectra with Gaussian or Lorentzian probability density functions
A method, based on binomial filtering, to estimate the noise level of an arbitrary, smoothed pure signal, contaminated with an additive, uncorrelated noise component is presented. If the noiseExpand

Radial motion in indirect time-of-flight range imaging causes instantaneous frequency shifts in the data. Instantaneous frequency estimation is a well studied topic, but existing methods are eitherExpand


The generation of diffusion Markovian processes with probability density function defined on part of the real axis
The approach presented provides excellent results in modeling significant non-Gaussian processes with approximately an exponential correlation function and is validated by direct numerical simulation of a uniformly distributed correlated process. Expand

Using Bayesian methods, estimates for the two noise levels are derived and it is argued that this allows better estimates of the underlying dynamical time series, and so better predictions of its future and of its fundamental dynamical properties. Expand
Computing the bivariate Gaussian probability integral
The closed form solution to the integral of the bivariate Gaussian probability density function over the four quadrants is derived using the characteristic function method in terms of the well-known confluent hypergeometric function. Expand
Supersymmetry in stochastic processes with higher-order time derivatives
Abstract A supersymmetric path-integral representation is developed for stochastic processes whose Langevin equation contains any number N of time derivatives, thus generalizing the presentlyExpand
Estimation based on entropy matching for generalized Gaussian PDF modeling
A novel method for estimating the shape factor of a generalized Gaussian probability density function that relies on matching the entropy of the modeled distribution with that of the empirical data is presented and assessed. Expand
General exact solution to the problem of the probability density for sums of random variables.
The exact explicit expression for the probability density p(N)(x) for a sum of N random, arbitrary correlated summands is obtained and it is shown that if the distribution is not stable, the profile is divided into three parts, namely a core, a tail, and a crossover from the core to the tail.

Quantum chaotic environments, the butterfly effect, and decoherence.
This work investigates the sensitivity of quantum systems that are chaotic in a classical limit to small perturbations of their equations of motion to find out whether this sensitivity is relevant to decoherence when the environment has a chaotic classical counterpart. Expand
