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. Because Webup the Fisher matrix knowing only your model and your measurement uncertainties; and that under certain standard assumptions, the Fisher matrix is the inverse of the covariance matrix. So all you have to do is set up the Fisher matrix and then invert it to obtain the covariance matrix (that is, the uncertainties on your model parameters).

When possible, report a Fisher-exact P value and …
