There is no measurement that can directly observe the wave function of a quantum mechanical system, but the wave function is still enormously useful as its (complex) square represents the probability ...
Nonparametric methods provide a flexible framework for estimating the probability density function of random variables without imposing a strict parametric model. By relying directly on observed data, ...
A new representation of a probability density function on the three dimensional rotation group, SO(3) is presented, which generalizes the exponential Fourier densities on the circle. As in the circle ...
