Convention of consistency. In accounting, the convention in consistency is a principle that the same accounting principles should be used for preparing financial statements over a number of time periods. [1][2] This enables the management to draw important conclusions regarding the working of the concern over a longer period. [3]
Consistency (statistics) In statistics, consistency of procedures, such as computing confidence intervals or conducting hypothesis tests, is a desired property of their behaviour as the number of items in the data set to which they are applied increases indefinitely. In particular, consistency requires that as the dataset size increases, the ...
Consistency. In classical, deductive logic, a consistent theory is one that does not lead to a logical contradiction. [1] A theory is consistent if there is no formula such that both and its negation are elements of the set of consequences of . Let be a set of closed sentences (informally "axioms") and the set of closed sentences provable from ...
Consistent and inconsistent equations. In mathematics and particularly in algebra, a system of equations (either linear or nonlinear) is called consistent if there is at least one set of values for the unknowns that satisfies each equation in the system—that is, when substituted into each of the equations, they make each equation hold true as ...
In statistics and research, internal consistency is typically a measure based on the correlations between different items on the same test (or the same subscale on a larger test). It measures whether several items that propose to measure the same general construct produce similar scores. For example, if a respondent expressed agreement with the ...
Consistency (database systems) In database systems, consistency (or correctness) refers to the requirement that any given database transaction must change affected data only in allowed ways. Any data written to the database must be valid according to all defined rules, including constraints, cascades, triggers, and any combination thereof.
In computer science, a consistency model specifies a contract between the programmer and a system, wherein the system guarantees that if the programmer follows the rules for operations on memory, memory will be consistent and the results of reading, writing, or updating memory will be predictable. Consistency models are used in distributed ...
Local consistency proves satisfiability in some restricted cases (see Complexity of constraint satisfaction#Restrictions). This is the case for some special kind of problems and/or for some kinds of local consistency. For example, enforcing arc consistency on binary acyclic problems allows for telling whether the problem is satisfiable.
