Alpha measures a stock's move during the month when the S&P 500 index is unchanged. For example, a stock with an alpha of 6 would be expected to rise 6% in a month when the price of the S&P 500 index doesn't change.
The extent to which an asset or portfolio's actual return exceeds or falls short of the expected return - the expected return is a function of the stock or portfolio's Beta. When positive, alpha is often referred to as "extraordinary" or "abnormal" returns.
Slow brainwave activity state of hypnosis (resting but awake). Also known as hypnoidal. Alpha is slower (deeper) than Beta, the awake state, and faster than Theta, a deep hypnotic state.
In computer graphics, the measure of a pixel's opacity. A pixel with the maximum alpha value is opaque, one with a value of zero is transparent, and one with an intermediate value is translucent.
A setting for the opacity of a certain pixel. A term for under development software or hardware products.
A fourth color component in the RGB color model that represents opacity. By changing Alpha values, images can be rendered completely transparent to completely opaque.
A value representing a pixel's degree of transparency. The more transparent a pixel, the less it hides the background against which the image is presented. In PNG, alpha is really the degree of opacity: zero alpha represents a completely transparent pixel, maximum alpha represents a completely opaque pixel. But most people refer to alpha as providing transparency information, not opacity information, and we continue that custom here.
The first letter in the Greek alphabet, answering to A, and hence used to denote the beginning.

Alpha is the test period during which the product is complete and usable in a test environment but not necessarily bug-free. It is the final chance to get verification from customers that the tradeoffs made in the final development stage are coherent.
Test version of software - game related or otherwise - that is a long way from being finished.
early testing stage of a software or hardware product; "alpha version"
emission 3/4 Particulate radiation consisting of fast moving helium nuclei (2 protons, 2 neutrons) produced by the disintegration of heavy nuclei of atomic number 52.
Alpha radiation is a heavy, very short range particle, and is actually an ejected helium nucleus. Alpha radiation is not able to penetrate human skin. Examples of some alpha emitters are: radium, radon, uranium, thorium.
a particle emitted from the nucleus of an atom, that contains two protons and two neutrons
A sub-atomic particle emitted from certain radioactive atoms when they decay. An alpha particle consists of two protons bonded to two neutrons.
the highest rank in the social order of each wolf pack. There are both alpha male and alpha female within each pack. Usually this pair are the parents of most of the other members of the pack, as generally only the Alpha pair mate. Alpha is the first letter in the Greek alphabet.
The top rank in the social order of the wolf pack. Since a separate social hierarchy exists for males and females, a pack has both an alpha male and an alpha female. They are usually the parents of most of the other members of the pack.
the dominant member (or pair) of a group such as a pack.
Term used to describe the highest ranked or most dominant individual of one's sex. Used of social animals: the alpha female of the wolf pack..
The user-specified upper bound on the probability of making a Type I error, i.e. P(reject H0 | H0 is true)
The probability of rejecting a null hypothesis when it is true (Type I error).
The probability of a Type I error. Represents the threshold for claiming statistical significance.
The set (and acceptable) probability that the null hypothesis is true. Psychologists typically set their alpha at .05. An alpha of less than .05 can be interpreted to mean that the differences are not due to sampling error.
Advanced 64 bit RISC (reduced instruction set computer - microprocessor that recognizes limited number of instructions) based CPU's from Digital Equipment Corporation.
RISC-based 64-bit CPU from DEC (Digital Equipment Corp.) It is designed to run with DOS/Windows, NT and Unix operating systems.
A RISC ( educed nstruction et omputer) architecture developed by Digital Equipment Corporation.
n. Digital Equipment Corporation's (DEC's) internal name for its 64-bit RISC-based microprocessor product introduced in February 1992 as the DECchip 21064. For trademark reasons, DEC has expanded the name to Alpha AXP, used as an adjective to describe the DECchip technology. The term Alpha is sometimes used in literature to describe the DECchip product, in such phrases as "Alpha-based computer." See also DECchip 21064.
A value used in hypotheses testing. Researchers use this value to determine whether or not a certain treatment or variable has an effect.
