Name  Description  

HasMethod 
Checks whether an object implements a method with the given name.
(Defined by ExtensionMethods.)  
IsEqual  Compares two objects for equality, performing an elementwise comparison if the elements are vectors or matrices. (Defined by Matrix.)  
ToT  Overloaded.
Converts an object into another type, irrespective of whether
the conversion can be done at compile time or not. This can be
used to convert generic types to numeric types during runtime.

In directional statistics, the von Mises–Fisher distribution is a probability distribution on the (p1)dimensional sphere in R^p. If p = 2 the distribution reduces to the von Mises distribution on the circle.
