Alpha Testing is always performed at the time of Acceptance Testing when developers test the product and project to check whether it meets the user requirements or not.Beta Testing is always performed at the time when software product and project are marketed.
The basic difference is that Alpha testing is performed within an organisation, Beta testing is performed outside an organisation.

What is the difference between Gamma and Beta burns?
"beta burns" are shallow surface burns
How gamma are members of the exponential family prove?
Think you've got this backwards. The exponential probability distribution is a gamma probability distribution only when the first parameter, k is set to 1. Consistent with the link below, if random variable X is distributed gamma(k,theta), then for gamma(1, theta), the random variable is distributed exponentially. The gamma function in the denominator is equal to 1 when k=1. The denominator will reduce to theta when k = 1. The first term will be X0 = 1. using t to represent theta, we have f(x,t) = 1/t*exp(-x/t) or we can substitute L = 1/t, and write an equivalent function: f(x;L) = L*exp(-L*x) for x > 0 See: http://en.wikipedia.org/wiki/Gamma_distribution [edit] To the untrained eye the question might seem backwards after a quick google search, yet qouting wikipedia lacks deeper insight in to the question: What the question is referring to is a class of functions that factor into the following form: f(y;theta) = s(y)t(theta)exp[a(y)b(theta)] = exp[a(y)b(theta) + c(theta) + d(y)] where a(y), d(y) are functions only reliant on y and where b(theta) and c(theta) are answers only reliant on theta, an unkown parameter. if a(y) = y, the distribution is said to be in "canonical form" and b(theta) is often called the "natural parameter" So taking the gamma density function, where alpha is a known shape parameter and the parameter of interest is beta, the scale parameter. The density function follows as: f(y;beta) = {(beta^alpha)*[y^(alpha - 1)]*exp[-y*beta]}/gamma(alpha) where gamma(alpha) is defined as (alpha - 1)! Hence the gamma-density can be factored as follows: f(y;beta) = {(beta^alpha)*[y^(alpha - 1)]*exp[-y*beta]}/gamma(alpha) =exp[alpha*log(beta) + (alpha-1)*log(y) - y*beta - log[gamma(alpha)] from the above expression, the canonical form follows if: a(y) = y b(theta) = -beta c(theta) = alpha*log(beta) d(y) = (alpha - 1)*log(y) - log[gamma(alpha)] which is sufficient to prove that gamma distributions are part of the exponential family.
What is the major difference between a mathematical model and an econometric model?
Mathematical model is exact in nature.it has Beta zero and Beta one and no stochastic or disturbance variables. Econometric model represents omitted variable, error in measurement and stochastic variables.
What is this year's forecast using trend adjusted double smoothing with alpha 0.2 and beta 0.1 if the forecast for last year was 56 the forecast for two years ago was 46 and the trend estima?
61.76
True or False For a given level of significance if the sample size is increased the probability of comitting a Type II error will increase?
The statement is false. For a fixed alpha, an increase in the sample size will cause a decrease in beta (but an increase in the power).
What is the difference between utorrent stable and beta?
Utorrent has an alpha and beta program. Alpha is for internal testing and is considered less stable. Beta is for outside use. Utorrent stable deviation allows for a percentage of errors but at this time is still most reliable.
Which is better alpha testing or beta testing?
alpha. it's a more private testing.
What is difference between beta and alpha test Brief?
A brief explanation of the difference between beta and alpha test is that alpha test is usually in-house and is part of basic development. Beta test is right before product release and typically includes customer input.
What is the difference between alpha and beta naphthol?
alpha naphthol with CCl4(carbon tetrachloride) gives blue colour whereas beta naphthol with CCl4 gives no colour. that is the distinction test between alpha and beta naphthol.
What is the Difference between alpha state and beta state?
The alpha state is a state of relaxed wakefulness with a slower brainwave frequency, usually occurring when a person is awake but relaxed. The beta state is a state of normal waking consciousness with a faster brainwave frequency, associated with alertness and focused mental activity.
What is the difference between alfa and bata?
do you mean alpha and beta? If so, this can be used in a number of ways. For example alpha testing and beta testing. Or first stage, and second stage. Something in alpha stage is probably an early prototype and so may have many problems. Once these are sorted it may become a beta prototype. At this point it will probably be more reliable... but is still not a final production version for release. You often hear these terms in software development.
How does alpha differ from beta when talking about a video game?
Basically alpha is a prototype stage of the game and beta is like a phase of testing.
How do you do alpha tests in aq worlds?
Alpha testing is over. It was an early testing stage of the game back in 2008, preceding beta.
How do you get to alpha in adventure quest worlds?
/majorepicfacepalm Alpha was a testing stage of the game. Not a map. It is impossible to obtain Alpha Pirate or Beta Berserker unless you were an Alpha/Beta tester like me.
What is the difference between an alpha and a beta?
Alpha is the first Greek letter. It can also mean the first in importance. Beta is the second Greek letter. It can also mean the second in importance.
How do you get beta berzerker in aqw?
You had to buy it during the alpha and beta testing stages of the game and is no longer available.
Difference between alfa beta testing in software engineering?
Alpha Testing: Alpha testing is testing of an application when development is nearing completion. Minor design changes can still be made as a result of alpha testing. Alpha testing is typically performed by a group that is independent of the design team, but still within the company, e.g. in-house software test engineers, or software QA engineers.Another DefinitionAlpha testing is final testing before the software is released to the general public. First, (and this is called the first phase of alpha testing), the software is tested by in-house developers. They use either debugger software, or hardware-assisted debuggers. The goal is to catch bugs quickly. Then, (and this is called second stage of alpha testing), the software is handed over to us, the software QA staff, for additional testing in an environment that is similar to the intended use. Beta Testing: Beta testing is testing an application when development and testing are essentially completed and final bugs and problems need to be found before the final release. Beta testing is typically performed by end-users or others, not programmers, software engineers, or test engineersAnother Definition:- Following alpha testing, "beta versions" of the software are released to a group of people, and limited public tests are performed, so that further testing can ensure the product has few bugs. Other times, beta versions are made available to the general public, in order to receive as much feedback as possible. The goal is to benefit the maximum number of future users.
