Chi-Square Statistic

A chi-square (χ2) statistic is a test that measures how a model compares to actual observed data. The data used in calculating a chi-square statistic must be random, raw, mutually exclusive, drawn from independent variables, and drawn from a large enough sample. For example, the results of tossing a fair coin meet these criteria.Chi-square tests are often used to test hypotheses. The chi-square statistic compares the size of any discrepancies between the expected results and the actual results, given the size of the sample and the number of variables in the relationship.For these tests, degrees of freedom are used to determine if a certain null hypothesis can be rejected based on the total number of variables and samples within the experiment. As with any statistic, the larger the sample size, the more reliable the results.

Rival Good

A rival good is a product or service that can only be consumed by one user or a limited number of users. The rivalry is among consumers, whose competition to obtain the good can create demand and drive up its price. A non-rival good, on the other hand, can be used simultaneously by many consumers.Most common household products and supermarket foods are rival goods. A bar of soap or a bottle of beer can only be consumed by a single person. If the product is in short supply, the rivalry among consumers is intensified. A limited-edition designer t-shirt is a rival good that may increase in price simply because demand outweighs supply.A non-rival good may be consumed by many people at the same time without any pressure on its supply. Streaming videos are an example.

Education IRA

Under this educational savings vehicle, parents and guardians are allowed to make nondeductible contributions to an education individual retirement account (IRA) for a child under the age of 18.

Vendor Financing

Vendor financing is a financial term that describes the lending of money by a vendor to a customer who uses that capital to purchase that specific vendor's product or service offerings.Sometimes called "trade credit," vendor financing usually takes the form of deferred loans from the vendor. It may also include a transfer of stock shares from the borrowing company to the vendor. Such loans typically carry higher interest rates than those associated with traditional bank loans.

Vendor Note

A vendor note is a short-term loan a vendor makes to a customer that is secured by goods the customer buys from the vendor. A vendor note is classified as a form of "vendor finance" or "vendor financing," which is a type of lending that usually takes the form of a deferred loan made by a vendor. Vendor notes are most likely to be employed when a vendor has more confidence in a customer's business prospects than a traditional lender (a bank) would.

Supply Chain Finance

Supply chain finance (SCF) is a term describing a set of technology-based solutions that aim to lower financing costs and improve business efficiency for buyers and sellers linked in a sales transaction. SCF methodologies work by automating transactions and tracking invoice approval and settlement processes, from initiation to completion. Under this paradigm, buyers agree to approve their suppliers' invoices for financing by a bank or other outside financier--often referred to as "factors." And by providing short-term credit that optimizes working capital and provides liquidity to both parties, SCF offers distinct advantages to all participants. While suppliers gain quicker access to money they are owed, buyers get more time to pay off their balances. On either side of the equation, the parties can use the cash on hand for other projects to keep their respective operations running smoothy.
