Spherical distribution

Web24. aug 2024 · While normal distribution is common for linear data, the von Mises-Fisher distribution is regularly considered for spherical data. The distribution is also known as Fisher distribution and assumes the data to be rotationally symmetric [ 3, 4 ]. Outliers are observations that are different in some way from the rest.
