Autoregressive Conditional Heteroskedasticity

A statistical measure of the average error between a best fit line and actual data that uses past data to predict future performance. General Autoaggressive Conditional Heteroskedasticity is the most common way of doing this. See also: Fractal Distribution.

Keen supposed that the median artery is a persistence of an embryonic artery [43] and Jaschtchinski called it an atavistic condition because it is usually found to contribute to the palmar arch (arcus palmaris) of certain lower animals [50].

[sup][11] Peripheral artery bypass is a good alternative in the vasoocclusive disease of the superficial palmar arch and tarsal arch, and also in relieving symptoms in lower limb larger arterial occlusive disease.
The ulnar artery on reaching the hand connects with the superficial palmar plexus which forms the superficial palmar arch. The median artery loses its connections with the superficial capillary plexus and is reduced to a small vessel.
The radial indicis artery may arise either from the princeps or from the deep palmar arch. The deep palmar arch, usually completed by the deep palmar branch of the ulnar artery, gives rise to three palmar metacarpal arteries that join the common palmar digital arteries off the superficial arch.
The ulnar branch of the superficial antebrachial artery persists independently, without its usual anastomosis to the branch of the axis atery, as the large lateral branch of the brachial artery and the superficial ulnar atery, which is found in the distal part of the forearm and joins the superficial palmar arch. If the brachial artery is taken to terminate into radial and interosseous arteries, the simpler embryological basis of the interosseous artery and the origin and course of the unusual branch of the brachial artery, replacing the ulnar artery, is the following.
Deep Palmar Arch: This arterial arch provides a second channel connecting the radial and ulnar arteries in the palm, the first one being the superficial palmar arch.
Association of the absence of the palmaris longus tendon with an anomalous superficial palmar arch in the human hand.
Thence it forms deep palmar arch in the palm after giving off the princeps pollicis and radialis indicis artery.
