# Von Mises Distribution

In probability theory and directional statistics, the von Mises distribution (also known as the circular normal distribution or Tikhonov distribution) is a continuous probability distribution on the circle. It is a close approximation to the wrapped normal distribution, which is the circular analogue of the normal distribution. A freely diffusing angle on a circle is a wrapped normally distributed random variable with an unwrapped variance that grows linearly in time. On the other hand, the von Mises distribution is the stationary distribution of a drift and diffusion process on the circle in a harmonic potential, i.e. with a preferred orientation. The von Mises distribution is the maximum entropy distribution for a given expectation value of . The von Mises distribution is a special case of the von Misesâ€“Fisher distribution on the N-dimensional sphere.

### Famous quotes containing the words von and/or distribution:

Everything perfect in its kind has to transcend its own kind, it must become something different and incomparable. In some notes the nightingale is still a bird; then it rises above its class and seems to suggest to every winged creature what singing is truly like.
—Johann Wolfgang Von Goethe (1749–1832)

In this distribution of functions, the scholar is the delegated intellect. In the right state, he is, Man Thinking. In the degenerate state, when the victim of society, he tends to become a mere thinker, or, still worse, the parrot of other men’s thinking.
Ralph Waldo Emerson (1803–1882)
