WebThe von Mises-Fisher distribution (vMF;Mardia & Jupp, 2009) is a natural and standard choice for densities in hyper-spheres. It is a two-parameter exponential family, one pa-rameter being a mean direction and the other a scalar con-centration, and it is symmetric about the former.

When the largest gas turbine manufacturer in the world needed a custom-engineered control valve that was hyper-accurate, able to choke flow at various travel positions, and had global service availability, Emerson took on the challenge.

Therefore, when the Fisher equation is written in the form i t = r t+1 + π t+1, it expresses an ex ante variable as the sum of two ex post variables.
