This project provides tools and implementations for recovering probability density functions using two distinct numerical approaches. It includes an interactive web application for visualization and ...

Densities for the angle Θ = uX(mod 2π) and the cosine $Y = \cos(uX)$ can be expressed, through Fourier methods, in terms of the characteristic function of X. Thus ...

Journal of Operator Theory, Vol. 65, No. 1 (Winter 2011), pp. 17-45 (29 pages) We introduce characteristic functions for certain contractive liftings of row contractions. These are multi-analytic ...
