Stochastic Functional Differential Equations On Manifolds, Rémi Léandre, Salah-Eldin A. Mohammed
Stochastic Functional Differential Equations On Manifolds, Rémi Léandre, Salah-Eldin A. Mohammed
Articles and Preprints
In this paper, we study stochastic functional differential equations (sfde's) whose solutions are constrained to live on a smooth compact Riemannian manifold. We prove the existence and uniqueness of solutions to such sfde's. We consider examples of geometrical sfde's and establish the smooth dependence of the solution on finite-dimensional parameters.
Empirical Spectral Analysis Of Random Number Generators, David Zeitler
Empirical Spectral Analysis Of Random Number Generators, David Zeitler
Dissertations
Computer simulation procedures have become a staple of research and development in many fields, including statistics. The generation of pseudo random number sequences is the core of computer simulation procedures. Validity of research results often depend on the underlying validity of the generator being used.
In this work we develop the machinery for a class of tests of spatial uniformity based on a multi-dimensional Fourier transform of the empirical probability density function. The test can be adapted to specific requirements and has the added advantage that it has computational complexity that is relatively independent of the number of data points …
Discrepancy Convergence For The Drunkard's Walk On The Sphere, Francis E. Su
Discrepancy Convergence For The Drunkard's Walk On The Sphere, Francis E. Su
All HMC Faculty Publications and Research
We analyze the drunkard's walk on the unit sphere with step size θ and show that the walk converges in order C/sin2(θ) steps in the discrepancy metric (C a constant). This is an application of techniques we develop for bounding the discrepancy of random walks on Gelfand pairs generated by bi-invariant measures. In such cases, Fourier analysis on the acting group admits tractable computations involving spherical functions. We advocate the use of discrepancy as a metric on probabilities for state spaces with isometric group actions.
A Bonanza Of Birthday Bewilderments, Dale K. Hathaway
A Bonanza Of Birthday Bewilderments, Dale K. Hathaway
Faculty Scholarship – Mathematics
The birthday problem is a popular probability conundrum at least partially because of the apparent counterintuitive result. But the results are not unexpected if the number of opportunities is considered. This article uses the opportunities approach to solve several variations of the birthday problem.
Reliability Studies Of The Skew Normal Distribution, Nicole Dawn Brown
Reliability Studies Of The Skew Normal Distribution, Nicole Dawn Brown
Electronic Theses and Dissertations
It has been observed in various practical applications that data do not conform to the normal distribution, which is symmetric with no skewness. The skew normal distribution proposed by Azzalini(1985) is appropriate for the analysis of data which is unimodal but exhibits some skewness. The skew normal distribution includes the normal distribution as a special case where the skewness parameter is zero. In this thesis, we study the structural properties of the skew normal distribution, with an emphasis on the reliability properties of the model. More specifically, we obtain the failure rate, the mean residual life function, and the reliability …
