Fisher distribution pdf
WebFisher distribution is a compact form of an exponential density model developed for random matrices, and the properties of the matrix Fisher distributions have been studied in di-rectional statistics [11], [12]. When applied to the special orthogonal group, the matrix Fisher distribution is defined by WebThe Fisher distribution is a continuous distribution that describes the proportion of a quotient of two variables that follow a chi-square distribution. Both variables are scaled …
