WebFeb 5, 2024 · The von Mises-Fisher distribution can be parameterized in terms of the location on a sphere. But this can also be parameterized in terms of spherical coordinates. For instance, we have for the von Mises distribution (the 2d special case) the two descriptions. in terms of the angle θ. f(θ; μθ, κ) = 1 2πI0(κ)eκcos ( θ − μθ) WebMay 12, 2015 · Fisher explained this derivation to W. S. Gosset (the original "Student") in a letter. Gosset attempted to publish it, giving Fisher full credit, but Pearson rejected the paper. Fisher's method, as applied to the substantially similar but more difficult problem of finding the distribution of a sample correlation coefficient, was eventually ... how to screen shot selection
