A product distribution is a probability distribution constructed as the distribution of the product of random variables having two other known distributions. Given two statistically independent random variables X and Y, the distribution of the random variable Z that is formed as the product = is a product distribution.
Distribution of products takes place through a marketing channel, also known as a distribution channel. A marketing channel is the people, organizations, and activities necessary to transfer the ownership of goods from the point of production to the point of consumption. It is the way products get to the end-user, the consumer.
Product category volume measures a firm's ability to convey a product to its customers in terms of total category sales among outlets carrying the brand. It helps marketers understand whether a given product is gaining distribution in outlets where customers look for its category, as opposed to simply high-traffic stores where the product may ...
Greek letters (e.g. θ, β) are commonly used to denote unknown parameters (population parameters). [3]A tilde (~) denotes "has the probability distribution of". Placing a hat, or caret (also known as a circumflex), over a true parameter denotes an estimator of it, e.g., ^ is an estimator for .
The i.i.d. assumption is also used in the central limit theorem, which states that the probability distribution of the sum (or average) of i.i.d. variables with finite variance approaches a normal distribution. [4] The i.i.d. assumption frequently arises in the context of sequences of random variables. Then, "independent and identically ...

A discrete probability distribution is the probability distribution of a random variable that can take on only a countable number of values [15] (almost surely) [16] which means that the probability of any event can be expressed as a (finite or countably infinite) sum: = (=), where is a countable set with () =.
The "passivity" agreement FDIC wants BlackRock to sign is designed to assure bank regulators that the giant money manager will remain a "passive" owner of an FDIC-supervised bank and won’t exert ...
